78 Trans Am alternator p/n help
Working on a 78 SE automatic W72 w/rear defrost but no a/c nor pwr windows.
Can someone tell me the correct alternator p/n for this application? The alt that's on the car is 1103058 (63 amp), with a date code 6 months after my car was built, so it's clearly not the original, but could it be a service replacement?? |

I'd say it's the 1102486 alternator?
HFR's link will help.

Look at your build sheet. Other than that, it’s a WAG

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world.
