[HIGHWAY BY THE SEA]

***UPDATE***

I picked up the 67 Chevy front clip from upstate on Friday. The first thing that I did was remove the original 67 Chevy wiring harness and install it into the 67 GMC to attempt to fix the aforementioned electrical gremlins. The headlights now work, as well as the gauge cluster lights, and I now have a small plastic junction block near the battery. Electrical problems almost solved!
The next day my son and I spent several hours dismantling the entire clip. Several of those evil fender clips BROKE when I attempted to remove them, so I had to crawl inside the clip and either use a crescent wrench, or vise grips to hold the broken clip nuts steady while my son used the ratchet on the other side. (I wonder how many gallons of P B Blaster we used?)
One of the bolts that attaches the inner fender to the bottom of the outer fender (no clip) kept slipping and rounding off when I tried to remove it. Just as I was about to drill out the bolt head, I instead used a chisel to break free the rust that was causing the ratchet to slip and the rounding off of the bolt. This worked and I did not have to drill it after all.
Yesterday we used P B Blaster on the windshield wiper motor and attachments, turned on the switch, then had a tug-of-war on either side of the truck to break it loose from a frozen state. This worked, and the wipers are now fully functional.
Then I turned my attention to the passenger-side door. The window did not want to roll down (no surprise) and the door handle only spun around, so we removed the handles and the door panel. I had to drill one panel bolt head off, then screw it INTO the door with a vise grip (and my hand inside the door) to remove it. This done, I greased the window crank assembly and the window now rolls up and down (still a little stiff).
After we completed this, I remembered a NOS door handle I found at a yard sale, and a NOS door handle “sender” that I found at a GM dealership . I installed those, and I have to say that I have NEVER felt a door handle work as well as this now does!
As soon as I get the turn-signal crescent female wiring plug from a board member I am going to tackle the turn signal problem next. Mine is broken in half, someone spliced wires into it, and some of these wires are no longer attached.
Since I still have not had any luck getting the truck actually started yet (turns over strongly) I am continuing to fine-tooth-comb the wiring (almost done) and get as much electrical things operational as possible. Absolutely NOTHING worked in this truck when I bought it. Not so much as a single light bulb. But that is no longer the case and this has been a learning experience for the both of us.
My son is desperate to see the truck start (as I am) but I am not going to rush this and have an electrical wiring fire (again).
