This site shows the B for early 8n's and the C for the side mount 8n's. any difference besides the mount plate?

Actually, Ron, the
early' 8N used VR #8N10505A up through S/N 1376684. Then #8N10505B through S/N 263,844. Then #8N10505C beginning with #308456. For replacement B applications, the regulators are supplied with a mounting bracket/adapter. Just for the record, the compromise in all this is that the A gen was 11.5A and the B & C were 20A, so currently, since there are no A VRs available, you are stuck with a 20A reg on your 11.5A A generator. That will be OK most of the time, since the current needs are typically small, however, a failed battery demanding more than 11.5A from the A gen/ B or C reg combination will over time over stress the A generator, since the later regs will only try to limit generator current to 20A. More than you wanted to know isn't it? :wink:
