Duster rear end compatibility

builder89 said
So I’m rebuilding a 70 duster and was wondering if a 73 charger rear end would fit and bolt up without any modifications needing to be done. Any info would be extremely helpful. Thanks

Bolt up, yes.. 'this is a jk, a lot of things will bolt up with hammer n crowbar'
right size ? No. Too wide.

Some people here need a 'reset'.
One argument too many and they become an ultra sensitive and overly critical butthole.

Fwiw I've used 8" ford rears... they do bolt up..just figure out your brake hose,cable and u joint.

go get yourself a book called..
Chrysler performance upgrades
it lists these dimensions/fitment details
