The bearings are marked "cau 6203/ps"
I'm finding tons of matches but none with the "/ps"...most have
"/rs" instead.
Anyone know exactly what I need?

Thanks for the link Greg! But no price listed and eternal shipping times make me think a local vendor is the better bet. Your link shows me they SHOULD be interchangeable with the "rs" bearings, but I want one to check before I buy from overseas.

I wasn't suggesting you buy from that site I liked the breakdown of what the suffixes meant. I
At one time sold a lot of bearings when I worked at a local auto parts/machine shop, but that was over 30 years ago so my memory on the meanings is not that good.

Exactly! It's been decades since I knew that stuff...but it turns out they are the same common 6203. All I'll have to find are the proper seals for the cases.
(The bigger crank journal needs the bigger seal)
