What is the correct alternator number on a 77 GP 400 . The one i have on is a 63A
1102854.looks original to the car,thanks

That is a 63 amp alternator for 77/78 with AC and rear defog.
There should be a date code on it which may help determine if original.

I would think it might be the original. Not sure what the lead time is for them.
