Diff Housing Narrowing In SoCal

Currie did my 8-3/4 and have done MANY 10” fords for our race truck over the years. They do exceptional work. Can’t say enough nice things about em. They did my 8-3/4 with ford ends and it saved me a bunch of money on Wilwood brakes.

Edited to add link with pics.
Why didn’t I build this years ago?
