Just thought I would pass this along.
Been narrowing Ford 9" rears for a little while now and had the opportunity to narrow an '72 8 3/4" A Body Dart rear.
Online measurements say they are 57 1/8" but, this rear is 57 3/4" drum to drum. The housing can be shortened 2 full inches on each side and use the original axles by cutting them off to fit because, each axle has 3 3/16 inch of usable spline and only needs 1" for the axle and rear to be fully engaged.
This leaves a drum to drum width of 53 3/4" to be used under a lot of hot rods.
Happy hunting
