i can get a big bearing jamsport box for around £600 then just take your diff to them to have put in at the same time .... half the price of cts.
im gunna look into doing an mt box conversion and fit a atb in that as over the years in different cars ive smashed about 15 gearboxs in rsts and cossies ect.
its all fun i blew up 4 diffs in a week in my mk2 escort lol bloody idiot doing burnouts lol
