When I took off the window guide for the convertible top that guides the rear of the quarter window, there was a rubber sticky insulation that was sandwiched between the window guide and the metal part of the convertible top frame.   I can't seem to find it anywhere.   I thought i could finde it at a hardware store since its just like a rubber insulation but its a bit thick and wide for standard household rubber insulation.

I thought it was just some sort of closed cell tape.  But its rubbery, and had a peel and stick backing, and the bolts went right thru it.
