Guys, I just looked at a 89. 60,000 miles on a crate 350 (f.i.). New warren hubs, new BFG 33x12.5. a/c, rebuilt tranny, ujoints, and diffs. He said the diffs don't have limited slip. Needs headliner. How much would I expect to pay to have lockers put in the diffs? His asking price is $5,000. Body is excellent, few dings and scratches, no rust.
