My used Enigma came with a brittle breaking one and i bought a new one for it. Can't remember how much, but i think it was the cheapest spanking new bit of kit i've ever got
It is not glued, just press in. It does alot of squishing to accommodate rdm or sdm. Working good now.
My footpad is lifting a little. Gotta find some good contact glue for that. I tried shoe glue, not sure if that is real contact glue or i didn't let it go tacky before sealing up. Might try it again - Huey may not allow leave time from beach to go to hardware just now
