Thanks Phil. Yes, I had read all the information on the Vitesse site, including the fitting instructions. I only started to feel uneasy when I knew the fitting instructions would not work for a Moss box car (very small opening in bulkhead for the torque tube) and therefore how could I be sure they would be accurate for my Rover 4 speed? Hence trying to find someone who has direct experience with this conversion. Vitesse were not exactly forthcoming when I asked if anyone had actually fitted the kit to a Rover 4 speed Plus 8.
