Here's what I have. The 63A one is a working alternator. It came off of a 1974 Nova. $30 shipped or make me an offer.

The 37A is just a core. I just took it off of my 67 k10. $20 shipped

no thanks rod not the right #s

it looks like that could be a 37a from a 70 v-8/400 or a 71 v8 454.

does that sound right to you rod? im just curious to see if my book is right.

Why would you want to put that alternator in a pickup truck. My records show that alternator goes in a 69 chevrolet cars, including Chevelle, Camaro and Novas. No record of this being put in trucks.

What would be the correct alternator code for a '72 402? Is there a production date for alternators?
