I am in the middle of a ls, 4l80, titan range box and np205 install. However I am at a stand still untIL I figured out if I'm ok mixing the polyurethane bushings on the adapter crossmember and the rear tourqe mount with the GM hydraulic motor mounts on the ls motor. I am consernd with the way thwyau flex at difftent rates diverting tourqe to places it may damage, like the tcase adapter or doubler. I have no experience with the hydraulic motor mounts but if they flex as much as the old gm rubber mounts there could be an issue. Now converting the motor mounts to polyurethane I'm not sure is posible, but I am going to see if they make one so all my bushing match. Any of you v8 swap guys running the hydraulic monuts with polly bushings on the tcase/ torque mount?

I would contact Motech in Las Vegas and see if they can help.
