Cool doc.
Any idea if the replacement alternator had the replacement # on it or the original #?

I would really expect the service number to be stamped otherwise there would be no need for a new number.

I found 681 in the service manual. wrong one on car so will look for correct one. All other numbers match like they should - car only has 41000 miles

If you understand how to use it, the Cross Reference Chart in the MPC will help you identify the OE p/n.
The Service p/n was for the bare alternator. It carried a specific p/n, you were expected to reuse your original pulley. A single Service p/n could therefore service multiple OE alternators. The OE alternators were supplied by Delco WITH the pulley so they carried their own specific p/ns and were application specific but were not serviced that way.. The OE alternator p/n for your application is listed in a few places. The Shop Manual may be correct but there is a '64 SCN (Issue No. 2 IIRC) that lists the OE alt p/ns. It revised certain info in the Shop Manual, not sure the alt p/ns were affected. Johnta1 might be able to help you out by posting a copy of the SCN page. |

They use the 10 DN alt with the separate voltage regulator..
