Cragar center caps (SBP)

Exactly! I appreciate you digging a little and you can see it’s a strange problem. I feel as though Cragar wouldn’t have made three different sized caps bc that’s logistics cost prohibitive but who knows. I’m constantly surprised by how auto manufacturers will switch parts out mid year or use stuff up from warehouses depending on where a car was built.

Assuming there are only two cap sizes, it seems the 13” wheel caps would work logically because the small bolt pattern wheels seems very specific to these cars. Prob wishful thinking, hopefully someone here will know the answer!

I agree, but in my younger days, I spent alot of time changing tires in a shop, using the Coates 2020 and 4040 machines, and I remember having to remove those caps to place the rim on the machine. The shaft fit thru the rims center hole, and you spun a lock down to keep the rim tight. I cant help but thinking that the center hole on most of these Cragar 5 spoke rims seem to be the same diameter.
If the diameter was different, it had to be very slight and not easily noticable.
