Have a 77 GMC crew cab dually that needs rear end. Prior owner put one in that is to narrow (wheel rub). There are a bunch of "correct" year 4.10's available. Found a unit from a 95 dually with 3.73. This would probably be a better ratio. Question is will the newer year be able to bolt up to the "old" style dually?

Craig, I don't have an answer for you but I think that Bill O'Grady at Vintage Chevy Truck in Fremont, CA would be able to tell you. He runs a 53-91 chevy only dismantling facility and is really knowledgeable about this stuff. Hope this helps.

Anything......I mean anything you need to now abou the 14 bolt rear end can be found at http://www.pirate4x4.com/tech/billavista/14b_bible/index.html

If it's not there, well then you don't need to know
