Just to clarify, I installed the OEM solid motor mounts replacements. I got them from SCP along with replacement tranny mounts and bushings. The passenger side was totally shot (see pics). I did the tranny mounts and bushings as well because they were worn out. I’m guessing the heat and being in Florida took its toll on them. I also did the BJH balancer at that time too. Sort of makes we wonder if it was slightly out of concentric.
If I'm lucky I won't have to do THAT again as it was a chore! About three years ago I had them done on my 90 the time the tranny was rebuilt becaue the driver's side was split. So much easier when the car's up on a lift and SOMEONE ELSE does it.
One of the new ones is also in the pics below.
