Just picked up this 1991 Z71 yesterday, wasting no time on fixing it up. Ordered quite a few parts on rockauto and also got a new set of Chevy take offs from a local dealer. Truck runs and drives good but has a bad cv axle so I’m going to replace both of them while I’m under it and also give it a tune up. It’s not a perfect truck by any means but really the only issues are cosmetics and I can fix those. Only rust in the truck is typical surface rust on the frame, both cab corners and some above the wheel trim on both bedsides.
