Re: early 80\'s restore... costs?
What model? (Chevy - Silverado, Scottsdale, Custom Deluxe; GMC - Sierra, High Sierra, Sierra Grande, Sierra Classic) What other options aside from A/C? Cruise, tilt wheel, PWs, PDLs, dual fuel tanks, cargo light, quad shocks in front...um, that's all I can think of right now. Does the 350 have a 4-brrl? Does the front axle have manually locking hubs or the original style automatic ones?
Shoot around here you can get a running 4x4 for $250 (mechanics special, but it'll go down the road). Otherwise ones that are in good shape bring a minimum of $1000 on auctions, up to $3000ish.
