Customs Caddy Hubcap info???

Trying to figure out what years Caddy Caps are the dip dish style that will fit a standard 15x8 reverse wheel. I know some have a inner attatchment ring and some have an outer (standard hubcap) attatchment ring. Pics would be great....Thanks, Alan

 

you can use a beauty ring first then the caps should work! love your buick by the way

 

My 53 sombreros use the inner attachment. Im going to be putting on dics brakes and found some 56& 57 deep dish caps . what rims will work for my 53 do i need to use a reverse dish.??

 

Is $100 a good price for a complete set of good shape caps?
