2-groove, 80amp Alternator for '69 C10 - can't find replacement - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi all -

My alternator needs to be replaced, but I can't seem to find a matching one for sale anywhere. I have a 2 groove pulley and it says it's an 80amp Alt. Delco Remy PN: 1100810.

Anyone know if this is NOT the OEM alternator for this pickup? Looks like most of the internet resources suggest a 1-groove 63amp alternator. Anyone know the OEM amperage of these alternators?

Do I need to swap pulleys from the old to the new and use a lower rated alternator?

Any help would be appreciated.
