Truthfully I'm surprised nobody has found a proper rebuilder that can cast new rubber in place of the old.

The cores are cheap and plentiful at this point.

 

Auto Atlanta had them on sale last year. The Collection parts department in Miami matched their price, so we just picked them up locally.

 

Not to beat a dead horse (though I'm about to), but as I have been staring at the mounts I bought from Roger (thanks again!) it occurred to me that when new might be a perfect time to fill in those holes with a silicone or urethane. It seems like opinions are a little divided on whether that would translate too much noise. I've still got some 50A urethane left from my 944 mount and, I don't know, should I? I'd be pretty happy if I never had to worry about replacing them again. Ugh, the indecision.

 

I have about 400 miles on the solid rebuilt mounts made by Waldo928 and I cannot sense any increased noise or vibration. That said, your new mounts should last until the year 2050.

I see you are in Nazareth as well, welcome.
