Now drivers side ones seem to be unobtainable but Bob does have new passenger side in stock. With no other option I ordered a passenger side one in the hope the motors were not handed.
Having stripped the mirrors down i can confirm that the motors are NOT handed so left fits right and right fits left. Also the ONLY difference in the powerfold bullet mirror and a standard bullet mirror is the motor itself. In short if you buy two N/S powerfold mirrors from Bob you can turn your standard mirrors into power folds in around 30 mins. I will leave it up to the individual to haggle with Bob but anyone interested pm me and I will let you know what I believe to be the lowest acceptable price
