perryseth's post in 1973 Fastback (71 351C) - I need help hooking up alternator!!! was marked as the answer
I got the DB Electrical universal alternator and it works like a champ!! I paid a couple of extra dollars ordering it through Amazon prime, but I got it in two days and I really like returning their stuff at Kohl’s because it saves a lot of time.
One wire right to the starter solenoid! I had to bore out the top hole in the alternator body so the long bolt would fit, and I had to add in a piece of a spacer as well. It’s a little bit off alignment so I’ll fix it later. Also- the adjustment bolt was a different size so I used an older bolt I had that fit. Ty again for the help
