When I removed the support from my 50 there were 2 pads, one had a shim
...pic... approx size 2 1/4x 2 1/4
3/16 thick
5/8 hole in center
I made my own replacements, as Drew posted you may need shims to get the body gaps right.
Funny thing is the Factory Assembly Manual shows only shims and spacers no pads.
