Yes finding the right pitch bolts in proper length is difficult in most places. I purchase hardened threaded rods for my stands and use nuts on the backside of the stand adaptor. Beats fussing around finding bolts in the right pitch, then fussing with proper lengths because some holes are blind while others are bore through.

the x member bolts do work though if you're not using them at the moment, but from the looks of your engine stand adaptor I'd say removing the clutch and FW are going to be necessary in your case as the stub arms look way too short on the adaptor to clear those components..
