Does anyone know where I can get a set of GM rubber mounts? I'd really like to stay away from poly and I've heard the aftermarket mounts are garbage. The engine is out, so I figure I may as well do them.

 

GM has not made these mounts in along time you might have difficulty finding GM made mounts. I got mine from Pepboys and there under a bigblock and are working fine.i dont like poly ether there to noisy and send to much residence noise through the car. I had a poly trans mount and it was loud inside my 99z28 there are some good.rubber mounts out there you just got to shop around.
