I can use some help here. Searched and found tips for full size wheel covers but have not found similar for the dog dish style caps as follows: I have Mercury and Lincoln wheels 1950 vintage and want to put 50 Merc caps on them. On a couple of wheels, the caps are tighter than a bull's butt but on two of them, they appear a bit loose and fear they may fly off going down the road. These are stock wheels and the caps are repop stainless. The wheels appear to be in good shape and on looking at them, can find no real faults with the tabs that hold the caps. Having had original steel Mercury caps many years ago, would like to avoid using them as they seem to be made of unobtanium that even when a specimen can be found is rusty. I will be getting the wheels powder coated so wonder if there is a way to remedy the "looser" wheels. Have you encountered this problem? If so what have you done? Thank you in advance!
