Did a GPZ1100UT engine fit into a Z1B frame without any modifications?

Want to do a GPZ1100UT engine swap but the lower end engine to frame mounts are missing at the GPZ1100 UT engine casting.
But the GPZ1100UT front frame tube got an extra engine to frame mount. What i have to do for my engine swap???

The lower left mount had a habit of loosening up. I guess that's why the switch.

Steve, i never had an issue of loosening up at the lower frame mount. I think i have to go the try and error way and have to bit the bullet.

Unitrack / 'J' non kickstart motors have slightly shorter crank cases and rubber bushes at the front so the engine mounts need modifying on the earlier frames.
They only did away with the lower mount because they rubber mounted the front just the same as Yamaha did with the LC ,YPVS etc.
A solid lower would have rendered the rubber mount ineffective.
