Just did my motor and trans mounts with zzp poly ones. I found it was helpful to use 2 jacks & wood under both the trans pan and the motor so I could lift it straight up. Lifting from just the oil pan was pushing the SLP crossover pipe back into the master cylinder. When I lowered it back down the motor had shifted forward 1/2" but once it was free of the jacks I just rocked it and it dropped in place. Despite the popular opinion I have zero vibrations at idle or acceleration. Shifts are much firmer as is the off-the-line move.
