HUNTER'S 1978 GMC C15 SIERRA BUILD THREAD
What I was afraid would happen is happening, I'm missing pictures in my file and things are getting out of order.. here's hoping to I'll catch up soon. Something I do remember however is how bad I wanted a rear sliding window. I really wanted the original aluminum framed ones but I just could not get ahold of one and ended up buying a brand new one from C.R Laurence. The part number was TSW850S and it was like $150 from amazon. It'll work better than any 40 year old unit I got somewhere else so it has that going for it.
