i am aware that volvo used the renault JC5 gearbox on a few volvo's....it's not great bit i believe that the M56 and M65 are much much better designed boxes. can you tell me if these boxes will bolt up to a renault block at all. the block being an F7P engine...it's ruuning a rebuilt JC5 with gripper diff at the moment but i was wondering if thses boxes might fit and be a worthy upgrade...

thanks for any help pics etc you may have...
