Thread: What Ford rear is this???

Tweet

The tag on the rear reads:

WDM-U 9HB

70 8 7 302A

WDM-U tells me it's a 8"....You have to use a wrench on the bottom two bolts, that's a 9"...It's a single ribbed case with no 'N'...Not a tapered axle housing.

Is it an 8", 8.8", or 9"...And what years and models does it come from. I'd like to completely redo the brakes.

And here's even more info;

Thanks guys for the quick response. Tech, that's the info I needed. Believe it or not, the Ford guys around my area couldn't answer that question, said their books don't go back that far.
