Hi Mark
I think you will struggle to do this although I believe it is possible. Andy Burnett can advise – his contact details are in the North Scotland section in FP – I’m sure he told me he had done it. Ultimately, however, I think you would be better off, certainly in terms of ease of doing it if not financially, replacing the outer drive shafts complete as I have recently done. You will then also have the choice of using good second hand double U/J types or new CV shafts.
