Internally regulated 3-wire alternator conversion - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I did this today on my 63' inline 6. I did not need to modify the alternator or brackets at all. It bolted right up. I had to find a nut because the top hole was not threaded on the new alternator.
I wired it just like above, including the wire to the + side of the battery, re-taped the harness and it is working and looking great.

The alternator came from Advanced Auto Parts. Their part number is 72929AV for the alternator and new connector is AC85841. $73.00+tax for everything.
(I used the link to a table I found in one of these threads for the alternators. This one is AC Delco part number 321-244. Clocked at 9 o'clock)

Thanks for all the info, I couldn't/wouldn't have even tried with out this forum.
