Another option is a modified 915 cross member from PMS with slotted bolt holes and a sturdy block provided to space it off the transmission so it just bolts up. This takes 915 engine/transmission mounts, which just bolt in. 915 engine/tranny mounts interchange - so you can use any aftermarket mounts as desired.

Another wrinkle when doing this in a 911 is that all 930 sway bars have a kink in them to clear the bigger transmission; pre-G50 911 rear sways don't. So you either source a 930 sway or space them off the ARB console (which allows a wider selection of sizes).
What am I missing here? I am running a G50 in my project car. I notched the torsion tube to clear the trans and everything bolted up fine with the G50 cross-member. I haven't tried to bolt on my rear sway bar yet.
