Well, I’ve been stuck at home all week iced in. I’m trying to get to the shop today and try to thaw things out. I’ll look when I get there at my parts books. I don’t think the pulley is a different size. If my memory serves me correctly, the pump for the TA is different. There was a discussion on Moparts about federal pumps awhile back. I just bought a pump, pulley and cooler that allegedly came off a TA. It was dated correctly.
