C&G Rubber Parts

[RalphG]

A while back I was inquiring here about replacing a missing rubber bump stop on the upper frame under the suspension arm of the 52 Merc. I got a couple of new ones from C&G Parts, reasonably priced. I recorded some video of opening up the mail package but neglected to video any of the installation. The reason was that the new rubber dropped into place in the frame with just some slight pressure by hand. So I'm wondering just how well it will stay in place. Might need to glue the rubber down to the frame with some "gorilla glue"?
