I've seen several auctions over the years from this seller - his prices are always way up there. I'd keep looking.
He wants more for this alternator than I have an original L78 block advertised for. Some people think gold is made from cast aluminum - I guess a few years ago, it could have been, when money flowed a little quicker. I have the same general problem trying to find a decent 814 alternator now -
Regards,
Steve
