Since the ’73 Dart came with a flimsy 7-1/4″ rear axle with only 4″ boltcircle axles, I decided to upgrade to an 8-3/4″ rear axle in case I ever decide to some upgrades in the engine compartment aswell.
Dodge Dart rear axles are narrower than all other Mopar rear axles. And since these rear ends are hard to find and high priced aswell I decided to narrow one of my fullsize Chrysler rear ends.
In order to properly shorten an axle housing, the cut off housing ends have to be aligned properly again against the axle’s third member.
Therefore I had to make a jig. I bought 2 large rounds of aluminium to turn these down on my lathe to create the alignment toolparts with.
