Quoted from John_in_NC:Damn, I tried. I have a Mayfair in waiting for restore with what looked like a replaced insert, I found the original in the cabinet base, I popped out the mismatched one without a keyline on it only to find it was a flat piece of plastic someone fit into the hole. I do have a bunch of these in a wall hanger El Dorado playfield but hate to wreck the look for one or two of the inserts. Now if you can make it worth my while with maybe a pbr ring kit for Quick Draw or Mayfair, I'd do it.
I thought they were 3/4" thinking that they were smaller than the reg 1" ones
I pulled a white one from an old pf a guess what TO SMALL! it is a 7/8" insert.
it is a odd ball size that I will be lucky to find in any color
