IF...you can find a 1957-59 FORD passenger car.....NOT a station wagon or a Ranchero...the 9" rearend housing will bolt right in a Gremlin/Hornet/Spirit...etc. First year the 9" was produced was 1957! There is only about 1/4"-1/2" difference in the spring pad spacing. Either pull the springs abit in the bushing...or elongate the pad holes a very small amount....as i did.Actually the total overall rearend width (wheel mount flange to wheel mount flange)is about 1/4" narrower.....so it makes for added tire space. I have one of these exact rearends in my 72 Gremlin...along with a 3.70 gear with a posi unit.I've used that exact rear housing in several auto's over the years. Getting HARD to find one at times...since the coupe/street rodders discovered them also!!!! Hope this helps,Joe Yahoo!
