HUNTER'S 1978 GMC C15 SIERRA BUILD THREAD
Been sometime since I added, so here we go.. still lots of catching up to do. This is when the "Might as well's" began. I decided I didn't like whatever the heck was going on with the firewall (undercoat and black paint) and I painted the back half of the frame so it was time to do the front.
My dad wrestled the transmission out of there (literally wrestled) and we started to scrub and scrape.. and scrub again and use some goo gone and some more scraping.. until we got 1/4th of the firewall cleared. Behind all that gunk was some cool chalk marks from factory.
BY THE WAY, I have since discovered attacking the undercoat dry with a gasket scraper to be the most effective. Doing it any other way with chemicals just makes it a sticky mess.
I'm not sure what the 266 means exactly, perhaps truck #266 for the day, week? If anyone knows it would be cool information to have under the belt.
