This might helpPeter: I'm leaning in the direction of replacing the 11 AC with the 127. If I understand correctly, the only serious issue is increasing the size of the main alternator cable? I've looked online and there are several "127 alternators" on the market. Is there a specific one that you recommend for this application (1972, 3500 auto)? The alternator in this car is mounted on the right hand side of the engine/ the left side if you are facing the car from the front. Is this considered a "right hand" mounted alternator? You had posted directions and a schematic of your car's electrical system earlier. I have this info. Thanks, Drew
I swapped my 11AC for an A127 and found it to be pretty straight forward. It bolted straight in and the pulleys lined up ok, the only thing was that there was not enough adjustment on the bracket to tension the standard belt. I was going to look for a shorter belt but found an old MGB bracket in the garage so I cut it in half and cut the end off the Rover bracket and welded them together. This gave me the extra adjustment and I could keep the standard belt.
Its the left hand one you need and it was cheaper than the voltage regulator for the 11AC.
Hope this helps
Dochie: Which A127 did you purchase? I've gone on line looking for "Lucas A 127 Alternators" and several show up. Of course, none have an application for a Rover. Thanks,Drew
