I have a brand new one wire alternator. It was suppsed to be for a Smallblock Ford but it turns out it's a Delco GM alternator part number 7127M. I would like to trade it for a known good one for a Smallblock Ford or sell outright for $75.
My March bracket setup is for a Ford alternator so I need to rerplace my current factory one with a one wire Ford case. The GM case has smaller holes for mounting (one of which goes thru the alternator and directly into the head) so I can't use it. There isn't enough meat around the hole (in my opinion) to open the hole and have enough structure around it to be durable.
