71 RR which altenator part number

general · Post by **general** » Fri Dec 14, 2007 9:29 pm

I don't have my buildsheet, trying to figure out which altenator I should be looking for. Car is a 440-6, 4 speed, no air, no power anything. I'm guessing it was the 37 amp altenator but I'm not sure. If someone out these has a car similar to mine with the original altenator. would you mind looking up the part number.
Thanks

OK, no one can tell me at least which altenator would have been standard on a RR. Is it the 37 amp or 50 amp. I can find the part number if I know which one it is.
