Thanks for the reply/suggestion. A stud mount of greater current rating may be the way to go. I could just drill out of the existing mounting holes and use the stud mount and a nut/washer combo.
However, after googling till my eyes fell asleep, I found a few sources on the web for the original diode - which turns out to be a 1N3492R. So that takes care of the diodes - Now, on to the caps. I mistyped last evening, as they are 17500uf and not 27000uf. Not as much luck, but I did find one supplier listing NOS Moto numbered caps on their web site. I requested pricing. Depending on the price, I will either buy them or retrofit a newer style cap.
