Ok, im giving up on my 93 Mustang in the sig and have decided to build up my 68 6cyl. Well, throw a 351 in there. anyways, was wonderin what is needed to be replaced in the rear end and where I can get most of the parts. Im lookin to get a 9" with a detroit locker, unless someone can talk me into the 9" withstanding 350 rwhp +. I am mechanincally inclined and do know some, just Im lost when it comes to carbs and interchangeability between cars.
