youre not hi-jacking at all mate!!
i dunno about the dimensions, its generally just bigger in every dirrection, but i guess the shafts being different lengths means the diff housing/diff is wider?
it is a fucking big lump compared to the BC box!
as for the escort GTI, i dunno, i assume its the same as the rs2k one, wouldnt have thought theyd change it if they didnt have to...
