wheel / hub cap fitment issue

[Kube]

Hello guys,

My guess is I have either the wrong wheels or the wrong hub caps...
1931. The ID of the wheel where the cap will be placed is 3 3/4".
The OD of the hubcaps I have is 4 1/8". The distance from one bent tab to the one opposite is 3 1/4".

Kind of a BB in a boxcar.
So, what say you?

Thanks.

I think the larger hub caps fit the early V8

Can you post some pictures?

Wrong hub caps.

Wrong hub caps.

So, you believe the hole in the rim is the correct diameter?

Photos would help. The Model A hub cap can be hard to put on and require the tabs to be bent in a little. That may be the problem.

What size are the rims? 21"? 19"? 18"? 17" 16"? Or?
