I was given a 1/2 ton 64 rear end with 3:73 gears and plan on putting it under the truck. I guess I would kind of end up with a heavy half. My intent is to build a driver but wish to get away from the old huck brakes and have a higher gear rearend. Has anyone tried this or does anyone forsee any problems? Thanks in advance for any input, OZ. | | |

Are your drums still in good shape? Good Huck drums are getting hard to find!
Current fleet (subject to change w/o notice) \'49 GMC 3/4-Ton , 60 Austin Healey Frog-eye Sprite (some assembly required), 2011 Dodge Avenger, 2015 Jeep Cherokee. No, they don't all run. My other ride is a (B737)no, (B767)no, A320.... Update... was Embraer E190, now Boeing B787. Knowledge is a wonderful thing, but ignorance means you don't know you can't do something.

For that year, my understanding is that the axel is narrower for the 1/2 ton than for the 3/4 ton, though I have never verified this for myself. As you probably know, the wheels go from 8 lug to 6 lug. | | |
