Nice Hinder.
I use the 9" in everything I build for play cars , and have no complaints.
Probably been a half dozen of them and I have yet to hurt one , from milder deals with 31 spline to 35 spline for the quicker cars.
Stock N cases at a minimum , but most got Strange with the 3.25 housing bore.
My first was an HRW case...........USA made back then.
But I don't think they are around anymore.
That was a hunk-o-iron.
