There are no aftermarket sets available. The best possible scenario for that rear is to find a 4.10 third member from a '67 to '72. It is a bolt in, but they are hard to find.
Use the search feature for more info. | | | | | Joined: May 2005 Posts: 8,878 . | | . Joined: May 2005 Posts: 8,878 | Lower gears are SLOWER gears.
Sounds like you're looking for higher, faster, gears; and the above advice is good.

These are out of a later 60s 3/4 ton and in addition to a better highway speed it really helped going through all the gears, just much better around town as well. | | | | | Joined: Dec 2007 Posts: 37 Wrench Fetcher | | Wrench Fetcher Joined: Dec 2007 Posts: 37 | Maybe you could put in a leaf spring 8 lug Dana 60 from a 70's truck. Not sure if the width is right. I think you can get a 3.50 gear set for the Dana. You can get a 3.23 gear set for a GM 14 bolt 8 lug truck rear end. Might be easier and cheaper though to conver it to 1/2 ton axles.

During my searches, the best I've been able to come up with is a 3.90 gearset for the 54 and that was with a later model center section. A torch and welder can make just about any late model rearend fit under your truck. Your best bet would be to start looking under 3/4 and 1 ton vans. Most of them already have 3.73 or 3.55 gears. I don't thing converting to a 1/2 rear of the same era would be real viable due to the fact they are torque tube setups and your 3/4 ton is most likely not. | | |
