Movement in the Drivetrain

LMs,
Type 3, engine is hard-mounted to and part of the chassis by the through-frame, through-engine bolts and, in theory, it cannot move. The drive shaft goes through three bulkhead bearings which are similarly bolted to the tunnel and therefore IT shouldn't move. The gear shift links forward to this unmoving transmission. In theory it SHOULDN'T move. The only part of the whole system that can or should move is the swing arm and rear wheel but, since the gear shift is at the opposite end, it shouldn't be affected. Post the long run described in my other post, the gear shit is vibrating frantically and fairly violently. I'm pulling out the upholstery to see if I can see where the vibration is coming from, but wondered if anyone had experienced and what specifically I should be looking for.
Also, has anyone employed polyurethane washers in the assembly to minimize "rattling" and to subdue the vibrations in the chassis. Understand, I've sat in mine for 44 hours so it had plenty of opportunity to observe and experience the vibrations. Specifically contemplating between the drive-shaft bulkhead bearings and the tunnel
