Mine has a different orientation of the part number and FoMoCo than Brant's. C5TA-18827-A2 number with a 452 at the bottom.Original alternator but not positive it's original to my car as it doesn't have the Hipo pulley.
John,As always, thank you so much for the explanation! Here are John's pictures:
Brant - I was talking about the alternator suppessors you posted above, which are in this thread. You'll see they have the same numbers as mine. Seems we've got a mix of volt reg & alternator suppressors discusions going on here.Good to hear you're starting a run of these too.
I only mention this because everything eles looks so nice and details are obviously a concern but FYI the OEM alterntors used different insulator coating on the stator. It was not the orangish Glyptal paint like the picture but a honey colored varnish type material. This is meant in a helpful way.
