I have a pair of Chevy 1-tons, a kingpin Dana 60 with disk brakes and Dana 70 with drums. Both have 4.88 gears and both are welded. Ready to bolt in and start wheeling. I'm looking to trade them for a set of Ford 1-tons (or any brand as long as they are driver's side differential). Not overly concerned with gear ratio, but the higher the better somewhere between 3.09 and 4.10. Kingpin preferred, but will seriously consider ball joint axles. If you're interested, shoot me a text at 830-931-5666.
