Mopar 8 3/4 Rear End (A-Body) - Questions & Help....

It looks like you have the u-bolts and shock plates, so just remove the old axle and bolt in the 8 3/4" axle...

The 8 3/4" axle is a little longer in the nose and you will have to get the drive shaft shortened to compensate...

Then slap on some new brakes and you're ready to go...
