Yes, live and learn. Had I placed a large flat washer under the mount, it would not have happened. I spent an afternoon trying to find a shop that would attempt to press it back in to no avail. I'm now overnighting two Wevo engine mounts (with the black bushings).

I looked at my trans mounts and I don't see any cracks, plus the 930 mount is different than the 911s... the 911s use the exact motor mount two-bolt flange, whereas the 930 has a nonservicable pressed in deal.
I did have some perceptible engine rock when I accelerated and had my hand on the shifter. Although it wasn't something I was going to address at this time, these mounts may tighten that up.
