I've been reading the FAQ stuff about the 9" rears. I recently purchased a 68 coupe that has a 289 in it but still the 7" rear so I'm starting to go over everything now.

So from this I can tell that the '68 uses a 54" Are any of the other widths usable?

 

get a lincoln versialle rear end from the junk yard. it is a a direct bolt on.

 

And most of them have disc brakes! A plus fo sho!!
