Cutting up a rear axle.

Truck Dana's work fine in our cars.

You make the drivers side axle tube 1 3/8" longer than pass side to get proper mopar pinion offset.

Side gears in the carrier may be strange, like 16 spline. You can get side gears to change the related axle spline if it has a sure grip in it. If you are going to spool it, never mind about this one.

I have a spreadsheet that calculates your housing length based on what you need for total width from wheel mount - wheel mount.
