Your link to Wheel Vintiques doesn't work properly for me. It doesn't look like they have the correct 54-55.5 cap anyway.

Jegs shows SKU 2030A: https://www.jegs.com/i/Wheel-Vintiques/939/2030-A/10002/-1

Should look like this: https://www.chevsofthe40s.com/detail/6410/Chevrolet_Hub_Cap_1954_12_Ton_Superior_Quality.html

Of course, maybe you prefer the earlier cap?
