Crossmember / transmission mount advise please

I wanted to install a Novak shifter and paint my crossmember .... Removed the crossmember (without supporting the transmission ) and saw the original transmission mount had completely dry-rotted. I ordered an after market transmission mount. Time lapse 1 month till I had time to put the jeep back together. As I put the crossmember back in place, with the transmission mount bolts passing through the crossmember - the entire crossmember now does not line up with the holes in the frame. It is off about an inch toward the passenger side. I assume 1 of 2 things are causing this: either the transmission shifted over an inch when it was not being supported, or the bolt positions for the new transmission mount are not the same as the original. Actually, it is hard for me to believe either of the 2 are possible, but I don't see any other reason for this misalignment.

The transmission mount is securely bolted to the underside of the t/c..... Would it be ok to cut off the transmission mount studs that pass through the crossmember? .... Just so I can get the crossmember to align with the frame?

Any input would be appreciated.

When the transmission dropped down it didn't drop straight down. Move the transmission back to where everything lines up. Don't cut anything.

These are the 4 bolts I have considered cutting off. They don't seem to serve any purpose.

Those bolts actually serve a very important purpose. They bolt the transmission mount to the transmission skid-plate. With out those attached, your transmission will bounce up and down every bump you hit

They do serve a purpose. They hold the rubber mount to skid plate.

The plate supports the transmission and T-Case, so when it went unsupported, gravity took over. That amount of time can cause more issues.

You could ask it nicely to move over. When that doesn't work, get a bar or 2x4 and ask it again.

Then you should also have hesitated to let all the weight of the TC transmission and motor hanging back to all be relying on your motor mounts and probably some wiring harnesses for that time. Move it back over, do not cut anything.

You let 400 lbs of transmission, bellhousing, and t-case force it out of place and temporarily deform the motor mounts, it won't hurt a thing to sweet talk it back into place with a bit of force.

The trick to that is jack the skid up and line it up on the 4 small studs in the mount, start the nuts on them and then work the whole mess into place on the frame bolts.
