F100 9" rear end width.....bronco same width???

Hey everyone I need to either rebuild or replace my toasted 9" and was curious if anyone knows the width of the 9" in a 1961 F100 or any 60's F100. Also want to know if anyone here knows if a bronco 9" is the same width as a F100 or what vehicle came with the same width rear end. Thanks in advance!

Most times you just need to replace the center "chunk". I believe 57-72 are the same size.

Bill will splian in more detail.

The 1966/77 Bronco's 9" axle housing is much shorter than any year F100. 1978/86, it's longer than 1957/72 F100's.

The 1961/72 F100 axle housing is the same length, but why replace the whole tamale?

All you need is the third member aka pumpkin.

Any 9" third member from a 1957/73 car, 1957/73 F100, 1969/73 E100 (Econoline), 1966/73 Bronco will work.

NOTE:

Some 1962/79 cars use an EIGHT INCH rear end...it looks very similar to a 9 inch.

1974/86 F100/150, Bronco & Econoline, 1974/79 Passenger Cars:

Some of these 9" rear ends have a tapered axle bearing/seal combination

I dunno if this type of bearing/seal combo will work with 1957/73 9" axle shafts, because I've never encountered this before.
