spoke to mark at mk motorsport and he says he might be able to make an adaptor to fit the diff, i guess somethng that fits between the diff and the car, he knows and has seen pics of the shell thankfully so he knows whats what, im to ring him on monday as hes going to have a look at a few bits he has up where he is, im sure he ll sort it, sounds like a good guy too,

thanks to all of you guys for the helpfulness, im not very good at this stuff but its great when others offer helpful advice and support
