Seems I saw info somewhere showing applications and widths of Ford nine inchers. Can anyone help?, Thanks, Bill

Bill -

Early Mustang (65-66) housings are 50" wide backing-plate to backing-plate. Only the 289 HiPo and GT350's came with a 9" - the housing is "necked down" on the ends where the U-bolts go. 1957 thru 1959 full-size Fords have the same dimensions, width and spring perch mountings. These housings are not necked down, and will come with 11.0" brakes (which can be swapped for 10.0" Mustang brakes if desired).

1967-1970 Mustang housings are 52" wide, and would have a 9" if factory equipped with 390, 428, BOSS 302, and even some 351's.

1971-73 Mustangs have a wider yet housing (may be 54", I can't remember). There would also be a fairly good number of intermediate Fords - Fairlanes, Torinos, Comets, and Montegos that could have a 9" rear end - these housings are wider than the Mustang.

regards,

Jeff

Bill;

Also, the 74 to 78 (not real sure about the years,but that is close) Lincoln Versailles had a 9 inch disc brake rear end the same width as the 65-66 Mustangs---50 inches....Still a few around.......

Thares is [or at least was] a good bit of 9" rear info posted at:

I've got several articles on the many and varied different 9" rears from Street Rodder and Rodder's Digest mags that I believe duplicates much of the info that is posted at this site. I might be able to dig out anything that's not on the website.

Thanks Dan, this is exactly what I was looking for. It helps explain why the nine incher under my car didn't fit in with the previous replies. It really helps me plan how to get theTorque Thrust D's I'm considering, to fit under my car. They are one piece with only one choice for backspacing. I need either a narrower rear and/or to have one shortened. The part about the axles is really helpful if shortening is needed. Thanks again for everyone's help, Bill
