66 4x4 front end
 

I have a 47 1/2 ton mounted on a 66 3/4 ton 4x4. I would like to completly change the front diff to a newer year so i can have disc brakes and newer style locking hubs? Any ideas for something that is interchangeable????

I put a Dana 44 axle out of a 76 Blazer in my 63. Works well.

You can use any axle from 1973 to 1991, from 1/2 ton to 1 ton pickup, blazer and suburban.
