Cutting a truck Dana 60 down for a a 70 challenger and can’t remember how much offset the tubes need from side to side anyone? Forgetfulness sucks!

If you are going to put big tires on the rear it would be wise to cut it to 68-70 b-body, or 67 b-body width, and use doc diff hangers. I would do it to any e-body.unless it was a 100 point car. 1-3/8" offset on the one I have.

I should be more clear, the drivers side tube is 1-3/8" longer, the offset may be a little less.

It shows 1 3/16” offset for most mopars, so I’ll use that. He “the owner” wants to stay with the wheels he has now.... he bought everything from The dr. Thanks for the help....

THIS ^^^^^^

The drivers tube is 1 3/8" longer which then places the pinion in the proper position.
