right, i have got the box out of the cossie and i have been told that it needs 2nd and 3rd gears, synchros and the couplings fucked, says its going to be 350 to fix it.

My question is, would it be worth my time to get a decent set of internals put in, the cars running 383bhp just now but moneys getting a bit tight, in fact its getting really tight! Building cars aint cheap! Can anyone recomend decent internals, rough costs and what is included, i dont know what i am looking for......i take it he means the centre diff is the coupling, i know the diffs knackered after seeing it on the rollers
