I have an 1981 with a 5.0L and C6 tranny. Holley 4bbl. It is has 3.50 gears. 4x4 works and I just put pivot bushings in the front end. I bought it with 3.00s up front and 3.50 in the rear. I got a donor truck with 3.50 took the front gears and t-case ( to make the speedometer match the gears). Right now I'll sell it for $550 cause I've yet to install the t-case (the Front gears are in and 4x4 works) and I have a carb rebuild kit I'll do here shortly. It is white and green with a good paint job but has fender rust. The interior is light green almost blueish. I'll be asking $1200 hundred after I finish what I'm planing to do to it and then putting it forsale near my house. Located in dover Delaware 302-223-6949
