Solid motor mounts ??? Do I have to run a poly trans mount? The reason I ask is with my yank trans cross member a poly mount will not line up with the hole in the cross member. If i remember right, it's been almost a year since I changed to the yank cross member, the stock bushing has an off-set built into it (the stud is off-set from the tranny mounting holes) and on the poly bushing the bolt holes are lined strait up. I can modify the cross member, but I don't have the tools to do it here at home, I'll have to wait till I get some time away from customer cars and do it at work.
So I guess the question here is what happens if you don't run a poly trans mount?

well i went and got the poly mount off the shelf and I think I can make it work here at the house by elongating the crossmember mounting holes some more and maybe a little on the mount. I won't know until I get the mounts in, I already took the stock ones off.
I'm still wondering why a poly mount would be needed with solid motor mounts and a relocated torque arm? It's not like there wil be much stress/load in the tailshaft area.

hmm, i'm running solid mounts with a yank trans crossmember and a poly tranny mount and it worked, but now that you mention it, I was wondering why I was havin issues gettin **** to line up when I put the poly mount in there, got it to work though w/o having to modify anything, so dunno.
If I remember correctly, I had to put the crossmember on the mount and then get all 4 bolts for the crossmember to the body started and then just tightened everything down and it pulled it all into place.

Got the spohn mounts in today after work and what a differance. I think the car is more pleasurable to drive now believe it or not. The car has darted around durring granny shifts ever since I put the locker in and the solid mounts cut all that out by more than half, and it doesn't buck around turns as much either. I guess the slack in the locker was shocking the stock mounts causeing the motor to torque to one side and then they would bounce back like rubber bands. I expected more vibrations, but it actually vibrates less now cause the exhaust isn't hitting the floor now.
The drivers side of the engine does get raised up a hair like I had heard, but it didn't affect anything. I didn't feel like messing with the poly mount, so I left the stock one in for now. Maybe some of you chassis builders lurking around here can answer my question about the negatives of the rubber mount for me?

It's just in every thread I found searching somebody said to put a poly tranny mount in with solids on the motor as if something would happen if you didn't.
