Thanks,Tim-
Nope-I couldn't find anything listed that has a 6.40 high range
This could be is a GMC only axle. Thanks for looking,and replying though. OH-One more thing-This Brownie has a military/really big truck speedo drive-the one with a hole for a "pin" with a "slot" in one side on one side. I need the "adapter" that converts the square drive speedo cable to it. It'll be a round pin with a blade,and will have one end that accepts a square speedo cable. (The cable housing nuts are the same.) I found one last year on eBay,but it sold before I had any money,and the guy didn't know where else to find one. Someone said, "Try the Ford Dealer-they used these for a hunnert years." Asked the oldest guy at their Parts counter,and he looked at me like I was from Mars.
