Dust caps for a 1951 Cranbrook

There are also some for sale on eBay.

I see on-line that the "common" replacement part manufacturer Dorman has one that is 1 13/16" wide, which is 1/16" wider than you need.
It fits Plymouths back to 1973.  The photo looks close.  Part number is 13996.  Check this one out.

Ya that one won't work. Needs to be 13/4 wide and 11/2 deep.

I think, but am not sure, that the dust caps that fit on 1933-48 Plymouths might be NAPA BK 7302409.

Would the '51 Cranbrook use the same dust cap? Also, the image on the NAPA Online doesn't really match my expectations, so the cross might be wrong. https://www.napaonline.com/en/p/BK_7302409?keywordInput=730+2409
