I was in a local junk yard in Phoenix over the weekend looking for some seat belts for my work truck and noticed at least two trucks with big blocks and they both had 781 heads on them. These trucks were the 73-81 years trucks. PM me if anyone wants the name of the yard. Also, anyone know where I can find seat belts for a 96 c2500 with bench seats? Dealer wants $200 for the female part of the seat belts and I was wondering if there is an after market supplier or cheaper oem. Everything in the bone yard was no good.
