The engine is under the car and ready to be installed, I was waiting for the arrival of my new PRG transmission mounts. Here they are ready to go.
I couldn't find the torque for these mounts so emailed Greg at PRG... 60 ft/lbs. He also mentioned a detail that might interest some of you who have these mounts.
"There is a crush sleeve, get the bolt tight, about 60lbs. The bolt torque has no relevance on the bushing preload. The bushings are set to a predetermined preload by the length of that sleeve. you could machine a longer or shorter crush sleeve if you wanted to try different settings "
