Can i remove transmission bushing and bolt it directly

hello i have a 89 yj with a butt load of lift, the one tons and 37s. i would like to make myself a nice tummy tuck. right now i have a trans drop kit in there to make the driveshaft angle slightly better. I was thing that if i take a nice piece of 3/8 steel and drill some holes i could make it my new cross member. i was also thinking that if i remove the transmission mount and bushings the transmission would still stay at the same angle and i would gain like 4 inchs of clearence. I would use the holes that mount the transmission bushing to bolt it to the crossmember. let me know what u guys think, thank you.

Are you running a CV style driveshaft or a standard driveshaft?

Do not solid mount the trans. You'll break it. It needs some movement. Also if you lift and tilt the motor mounts it will angle the rear output a bit more.

its a bit different than this at the present time, but u can basically see the distance and the angle that has to be worked with. the stock cross member with tcase drop is a perfect height, but i would like to increase my clearence

It looks to me like your transfer case needs to be raised a little bit anyway. With CV your pinion angle needs to be 1-2 degrees below your drive shaft angle. IIRC.........

The trans mount is mounted to the casted aluminim case. You can crack the trans case right at the bolt mounts. You don't need too much bushing but it does need some movement.

You could mount the crossmember to the trans solid and add bushing mounts between the frame and crossmember on both sides.

Drop your pinion angle a bit, remove the tcase drop and you should be fine.

Oh, and put your shock back on, I see its sitting on the ground there....

So, seriously, why would you post a pic if its not how "it actually is"?
Im basing my post around a wrong picture....

So, go drive 500 miles to your Jeep, and take another pic of how it "actually is" then get back to us...

IMO: you NEED some sort of mount between your tcase and cross~member, otherwise, every time you hit the throttle, engine torque will rip your mount bolts right out of the cross~member.
Ever goose the throttle in neutral while under the hood? the whole engine assembly moves, that is also happening to the transmission and tcase, with no buffer (mount) you will rip things apart quickly.

Oh, i only commented on the shock because in your wrong pic there is a shock sitting on the ground.

i already got all the steal and stuff neccasary to make it, my problem with the pre made tummy tucks is the face that it raises the transmission 2inchs higher than stock and i cant have that, im gonna find a nice low prof bushing. I actually ripped out 3 transmissions mounts, every time i go wheeling one breaks... It completely rips out of the ruber
