Last night I replaced my solid engine mounts with club sport/cab type from our host. Replaced all the hardware too. Wanted to take some of the strain off the motor since it is not a track car anymore. Was one of the easiest things I've done. I made sure that the engine was well supported then did one at a time. Everything lined up perfect the first time. I'm going to owe the repair gods big time on my next repair.
Initial impression is that some of the vibration has been reduced and no difference with shift quality.
I left the transmission mounts solid for now.
