Attention owner of the purple stepside on the previous page: PLEASE tell me you fixed the rust and the bed?!? Pretty please! My 77c15 namesake comes from a primered example extremely similar to your truck. I traded a perfectly decent 77 c10 for that hunk of junk. Ran it once, burned the tires off, parked it, then traded it back.
I sold that truck for 1500, 4 months later I bought it back for 500.
