I believe there are some chrome plating shops that will polish what you have and make it look better.
I'm sure the cost is less than chrome plating but I do not know the cost relative to chrome plating.

Great job! I believe you have very nice looking caps now.

Thanks but I do have the Originals. They are a bit scratched. I guess I will polish them up and use them this way. See Picture.

I am certain that ANY Chrome Shop will tell you that the process of re-chroming your caps would outweigh the value of the cap. Best bet is to find some that will suit your needs. I do have some caps in storage and would be willing to look for them next time there if you are interested.
Also, there are several sized caps. Some for the 15 inch wheels and some for the 16 inch. Measure the open area on the backside of your cap to see if they are 9 or 10 inches across.

Thank you that makes sense now. That is what mine are. Do you know how one would go about re-chroming them?

In my experience, the original caps are simply metal, with a chromed metal "skin" attached them. NO stainless associated with the caps what so ever.

Are 1948 Hub Caps Chrome or Stainless Steel? 1948 Special Deluxe Coupe.
