thanks , i found one that was built for a mustang with disc brakes for 200$ but im kinda leary because the guy cant tell me anything about it all he can tell me is that is was supposed to go in a mustang and the guy gave it to him in trade for some tat work!??! i measured it but i just measured from inside disc to inside disc. i think i would be better off buying a housing from my buddy for 100$ and have the tubes shortenedfor 140$ and order new axles and gear assembly. i just wished there was a cheaper way cause all together im lookin at 1200-1800$. im lazy and about broke but i want a good rearend,im only runnin 300hrse.anybody got anything like that??? thanks again
