I need to replace the alternator in my 1972 510. The original owner modified it such that the voltage regulator assembly and associated wiring had been removed, so he had used what I believe to be an alternator from a late 1980s Eagle Medallion. Given what has been removed and modified, do any of you have any concrete recommendations for a replacement part? What would be very helpful would be a supplier and part number if possible, especially if you have had experience with such a thing.

Thank you very much in advance,

Matt

a maxima or 240sx alternator is almost bolt-on, and a quest alternator is pretty easy to fit also.
