[BaadAssGremlins] Re: Motorola Alternators and Prestolite ignition modules

["Dan M." <vegadan@xxxxxxxxx>]

Doc,

I'm gonna chime in hear and ask what may sound like a real stupid
question.  I checked my 77 amx w/258 and discovered that I have a
delco alt on the passenger side, under the a/c compressor.  Is it a
simple swap to a 100 amp delco unit, or is there more to it?

Thanks,
Dan
