I have the opportunity to buy a fully built 8.8 rearend off a 2002 GT for $400. It has all the goodies (spool, c-clip eliminators, 31 spline axles, 3.55 gears, TA girdle, slotted rotors, etc). I eventually did want a 5-lug conversion for my LX. I know these rearends are longer than fox rear ends and will bolt up. Yet I wanted to know if anyone knew what would be a good backspacing for some Prostars (15x8's) to fit nicely under the fenders and not stick out? Also as far as braking goes..I would need a new master cylinder off a 95+ stang, and a proportioning valve..is this correct? Any help or recommendations would help alot..thanks.
