hey guys
im in need of some info, i currently ripped my 323i 1984 motor out and replaced it with a rb20 skyline motor (ALOT MORE POWER!!!!!) but now im afraid of busting the diff as iv done it once before so i was wondering what will bolt straight on? where i can get a cheap diff to australia? and finding some re enforced driveshafts as they are breakin down like a kazaksthan donkey owned by the town rapist in borat!!!
all help would be useful cause there are a few ppl here that have worked with them and they are as good as a one armed brick layer from baghdad.

THANKS FOR YOUR TIME AND APPRECIATE THE HELP.
