1972 C10 Alternator Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Cam1968rsss** · 08-25-2016, 09:22 AM

Hi all, need some expert help. Have a 1972 Super SWB that I am restoring, trying to find out what the casting number would be for a 60-63 amp alternator (or what the correct amp would be).

Thanks
Eddie

I have three of them:

63 amp 1100876 The 7 might be a 3 it was hard to read.
8J6--12 V Neg----------> this on was on the casting not sure what it means.
I understand the 12 v negative ground

61 amp 1100849
2B2512 -----------> this number was on the casting not sure what it means

34 amp 1100834
illegible

Hope this helps. VV
