Bj 74 rear axle swap to 60 series

[toms42]

Gday looking to swap a 60 series axle housing into the rear of my bj any one know the distance from the axle locating holes on the spring mounts of a mwb axle housing to the flange where the backing plate bolts on?

Tom why do you want to do this mod just wondering.

Wider axle rears easy to swap just weld on new spring perches, doing an ifs hub on frt to make it wider to match the back.

Ok
I have a few good 40 housings kicking around not to worry.

I too want to learn... What are the benefits of an 80 60 or 40? And why choose the 60?

60 close to 3 inches wider and are readily available 80 wider again but are coil and small diff frt and 40 are either narrower or the same cant remember.

the rear is easy just cut and weld new perches, the front is the harder end to do the Rh side perch has to be welded up onto the diff unless you outboard the springs
