I am looking for a alternator # 1100691, 32 amps. Needs to be dated Nov-Dec 1966. I think the 1100691 was used on all '67 buick V8s without A/C so it is not unique to the GS and is not necessarily rare.
I have a 1100691 42A alternator dated 7 a 24. If interested, you can reach me at manelis@netzero.net John
