I remember seeing an article in one of the past issues that went through the swap of an externally regulated alternator to an internally regulated alternator. I believe the conversion was done in a '70-'72 Chevelle. I also believe that there was a schematic provided for the changes that needed to be made as well as GM part numbers for the alternators. If anyone recalls which issue this is in or can point me to somewhere else on the web that provides this info, I would appreciate it. I'd like to do the conversion for my 72 Monte Carlo. Thanks.
