Tahlequah, OK
Hey, I am doing my 5-lug conversion. I've got a complete rear-assembly out of a '95 stang. axles, etc. the 8.8 with 3.08 gears / posi-track

Only thing is it's been sitting out in the open for half a year. looks pretty rusty. I don't have any experience messing with rear diffs .... any of you guys have experience with old differentials... i don't even know what kind of metal it's made out of. should i sand it down...

I think i've seen some guys powder coat them..

anyway, i'm just talking out of my ass. :shrug: go ahead and give me some advice. :eek:

The center housing is cast iron, the tubes are steel. Cover the axles and wire bush or sandblast it to clean it up.

Clue: use a magnet to tell iron and steel from aluminum. Aluminum is not attracted to a magnet.
 
I thought sn95 axles were wider than fox axles?

They are 3/4" longer on each side. Everything still fits OK. Some extra wide wheels may need a different offset to prevent the tire from rubbing on the inner fender. Sometimes the fix for this is to roll the lip on the inner fender.
