This is an interesting topic because I was just looking into the same thing. This is the center of the wheel of my 1936 Dodge D2 4 Door As you can see, there are spring-clips in the center for the hubcaps. This is the outside view of hubcap listed on Ebay for a '36 Dodge This is the backside view of hubcap listed on Ebay for a '36 Dodge This is the outside view of hubcap listed on Ebay for a '34 OR '35 Dodge This is the backside view of hubcap listed on Ebay for a '34 OR '35 Dodge From what I have seen, it's nearly impossible to tell the difference between the '34, '35, or '36 hubcaps unless you turn them over. At any rate, these hubcaps are NOT chromed. They have a thin skin of stainless steel that is crimped all the way around the plain steel hubcap. They can easily be polished to a chrome-like shine. However, you can not remove any dents by hammering on the inside. To get any dents out, you have to uncrimp the skin, carefully tap out any dents, then crimp it back on. Not impossible, but very time consuming.
