    Any one know what WmS-WMS measurement is on my 74 duster 8 1/4?

    saw some charts but guys said they weren’t accurate.

    thanks,

    The chart you’re looking at is actually accurate with respect to the width of the 8.25” rear end (it is garbage for many of the measurements it provides).

    At any rate, the housing should be 51.5” flange to flange, or ~56 3/4” wms-wms for the complete rear end with drums.

        The 8 1/4 rear especially is very narrow for a Duster. I hope your other rear is actually a little wider, especially if you are not moving the springs in. This is why a lot of people put B-body 8 3/4's in Dusters/Demons/Dart Sports
