My name is Chris, I have a 79 K5 with a 4 in lift on 35's. It's got a a 3/4 ton set up, dana 44 in the front, GM 14 bolt in the rear. Had this truck for 2 years now, it pretty good but needs a little work, they all do! Anyway I saw you section on modifying 81-91 dash to fit 73-80 trucks, and was pretty impressed. So I figure you guys were the experts I need.
