    Getting ready for Woodward, a '70 Chevelle build log

    I know it's been a while, but I figured I'd post this one. It was a fun build for one of my regular customers.
    In the past I've done his '15 Navigator, his '15 MB S550 and now the Chevelle he just bought. Hopefully,
    next will be his '13 Bentley Continental GT Speed...we're already talking about it.

    Also, this is my first forum post with my new Macbook Pro. lol

    Let's get to it.

    The car is a 1970 Chevrolet Chevelle. Original Blue/blue interior big block car, but it currently has a 502 Ram Jet crate motor in it,
    backed up by a 4L80E, electronic 4 speed auto w/ overdrive. 10 Bolt rear end. It came in with manual windows, locks and trunk.
    The original HVAC system was mostly missing, with only the fan and floor working.

    It had no audio in it. It did have a set of Autometer gauges in a plastic dash overlay that had some fitment issues.
    The opening around the left side dash vent was too tight to allow the up/down adjustment lever to move freely, and the opening around
    the wiper switch would let the wiper switch go into Hi. Also, whatever genius put it in, epoxied some silver painted aluminum trim pieces over the screws
    that allow you to remove the dash. Sigh.

    IMG_20180628_151519159_HDR by Jay McGraw, on Flickr

    Here I've marked where I want to cut the wiper switch opening...

    IMG_20180628_151500946 by Jay McGraw, on Flickr

    I made a jig similar to what you'd use for pressed grills, and a piece of 1/16" Kydex to reform the openings for the dash went and wiper switch.

    And molded them in.

    Followed by SEM Texture coat and flat black paint. I also had to cut out the center air vent for the upcoming Restomod Air installation.

    Re: Getting ready for Woodward, a '70 Chevelle build log

    When I began running wires for the Alarm/Remote Start with phone interface, I ran into a problem.
    I needed to run my wires out through the firewall for the siren and hood pin switch. Someone had built
    a stainless steel box that was tucked down under the Ring Bros. hood hinge on the driver's side. It was held
    on with an old Chrysler door panel clip (that the hole in the firewall hole was too big for) and a 1" square of
    velcro.

    I needed to remove it, but it was such a tight fit, I had to unbolt the hinge to get it out.

    Before:

    IMG_20180629_150107530 by Jay McGraw, on Flickr

    IMG_20180629_150101283 by Jay McGraw, on Flickr

    So, I took it out, and it was hiding the coil. I needed to put it back in, but it fit horribly, so I made some modifications.
    I notched it so the gas strut for the hood hinge wasn't rubbing on the box anymore. Then I used the piece I cut off of it to make a bracket for mounting.
    I pop-riveted it on and then used a rivnut to bolt it on the firewall with a stainless Allen head screw.

    IMG_20180630_085611486 by Jay McGraw, on Flickr

    Moving on from there, we installed power windows and locks. The power window kit came from Nurelics.com and bolted in to the factory locations.
    Came with a new harness all done up with Techflex and old style chrome GM switches. But I needed to get wires from inside the car to inside the door.
    And the boots they provide are small and don't look quite right to me. So I took a trip to the junkyard and grabbed some door boots off a mid-late 90's Astro van.
    I also picked up the proper sized hole-saw to make the holes. But you know what? The holesaw just didn't fit in there with the door on, so...

    IMG_20180703_100727897 by Jay McGraw, on Flickr

    IMG_20180703_100733744 by Jay McGraw, on Flickr

    I like these because they're round and have a decent amount of room, in case we do something later.

    While I was at the junkyard, I grabbed the lock switches and pigtails from an '86 Cutlass 4 door (mainly for the pigtails and retainer clips) and ordered new switches from Amazon. Oops, didn't any pics of the final product. Had to place the window switches to cover the holes left by the window cranks, and put the lock switches toward the top front of the door. Looked factory when I was done.

    The NuRelics kit works well, but the instructions were vague. I spent about 6 hours on the driver's door, before I realized I didn't need to remove (or spend hours adjusting) the glass. The rest of the car took about 2.5 hrs. I initially used DEI heavy duty actuators for the locks. However, on my day off someone moved the car and didn't notice
    that one of the lock switches was stuck in the up position and burned out both actuators. I work with idiots. Replaced them with Omega R&D DS2.1 actuators, since we had special ordered the DEI ones in.

    I also added a power trunk release from Original Parts Group.
    Only minor trimming of the trunk lid was required. Rustoleum Regal Red was an almost perfect match to the paint on the car,
    so I used it to paint over anywhere I had to cut metal.

    IMG_20180719_193022925_HDR by Jay McGraw, on Flickr

    So, now the car has Power windows, power locks, power trunk, alarm, remote start, 2-stage unlock, and I added a retained accessory power circuit for the radio.
    Almost like a modern car.

    Now on to the fun part...speakers.

    The front got Focal KRX3 3 way components. Absolutely gorgeous speakers. I made custom plates for the dash speakers to hold the 3"/tweeter.
    They bolt in with brackets I made from 16ga steel that bolt to the factory front bolt holes and one of the dash mounting bolts on the sides.

    IMG_20180709_115918669 by Jay McGraw, on Flickr

    IMG_20180709_120206921 by Jay McGraw, on Flickr

    I ended up mounting the 3" under the plate so I didn't have to worry about it hitting the dash, and I finished it in spray on bedliner.
    I added some foam around the mid to help seal it to the bottom of the stock dash.

    IMG_20180719_192958743_HDR by Jay McGraw, on Flickr

    Originally, I was going to do the A/C Install, and I contacted Restomod Air while doing research. I asked Gary over there if me putting speakers in the
    fresh air intake (passenger side kick panel area) would interfere with the A/C. He said no. Vintage Air's kit runs A/C lines right through that spot.
    Meanwhile, the customer talked to the place he bought the car from and they said they could do it, and I felt that would be a good idea since I had a guy quit and was short staffed at this point. I emailed him all the stuff he'd need, so hopefully they don't screw it up. I'm wondering how much stuff I'm going to have to fix after they're done.

    But anyway, the midbasses went into the kick panel area. I would have preferred to use plastic for the mounting plates, but we didn't have any, it's a PITA to get my boss to get me any and it's a nice weather driver anyway, so I went with wood and bedliner. It works for Bing. lol. I also used Kydex to make splash guards for the speakers as well.

    IMG_20180719_121618531_HDR by Jay McGraw, on Flickr

    And since the stock kicks would have looked silly (since they didn't match) I made new ones. With pressed grills. And chrome trim. And sexiness. lol

    A little more work after that and I wrapped them in black vinyl. I used black flock on the area under the grill.
    I wrapped the trim rings in chrome vinyl. They came out OK. I think the lady at the vinyl shop gave me something
    other than what I asked for. The car is coming back in spring for trunk trim and air ride, so I'll figure something out
    by then. Anyway, on to the pics...

    We also did the new Alpine Halo9 HU in the dash.

    Then we move on to the back...

    For the rear speakers we did Focal KRX2 2 way components. The car already had a flat, black vinyl covered rear deck in it, so I made some grilles to compliment the fronts that simply attach to it.

    I had to cut metal for the speakers to fit, and for no other reason that it had 6x9's stock, that's what I cut the hole to. It also gave me a little room to play with if need be.

    Re: Getting ready for Woodward, a '70 Chevelle build log

    So, the customer had a Kicker L7 12" Q series in his Navigator, and really liked it. I didn't have room for a pair of 12's, so we did a pair of 10's.
    Initially, we planned to do ported, but didn't have room, so we went sealed. The sub box/amp rack and temporary anyway. He bought the car and brought it to us the next day. I was worried he wouldn't like it, but I was wrong. He loved it. Couldn't believe the output. The other installer was in the bathroom like 40 feet away and said he could feel it when we fired it up. lol.

    The customer really wants to drive it. lol It's going to get revamped in spring.

    The stack fab notches are to clear the rear deck speakers.
    We fired the box into the cabin, to reduce the trunk lid rattling. Customer didn't want deadener on the trunk lid.

    Nothing too crazy, but it really does sound good. I'm not usually a Kicker L7 fan, either.

    Then there's the amp rack...

    The amp rack is a simple affair. It holds the passive crossovers for the 2 sets of Focal speakers, as well as the Arc Audio 2300SE and 4200SE amps that power the system.
    Interior is sprayed with bedliner. I took measurements for a trim panel, that I may try to build if I get some free time. He'll probably stop by for the Woodward Dream Cruise since our store is right on Woodward. If he's going to show it off, I'll put that on. I'll probably use some of the magnets I got from Joey@12vtools that hold all the speaker grills on.

    The box has 4 1/4"-20 threaded inserts in the back of it that the amp rack bolts to. The amp rack also has threaded inserts in it that let me run bolts through the trunk hinge support into the amp rack so none of it can move.

    All the speaker wire is 12ga OFC copper, RCA's are Stinger, IIRC.

    IMG_20180728_145722242_HDR by Jay McGraw, on Flickr

    I was actually really impressed. The car sounded great. Customer loved it.
    That's really all that matters.
