[Fot] Gearbox mounts

Shane, 

I made Derin (acetal) rear motor mount for our TR4 tranny.

It is the size and shape of the tranny mount pad, drilled through the 
crossmember and secured with bolts and fastened with Nyloks with no compression on 
the Delrin.

The front is stock mounting pieces with the TR4 Torque Reaction Arm that 
limits the EXTREME rotation of the engine, which occurs at FULL OFF throttle and 
braking following FULL ON  throttle.  The TRA does a good job of dampening & 
limiting the rotation of the engine.

Like I told Henry, everyone seems to have a different experience, but this 
works for me. I got tired of failures.

If enough folks are interested in a CoPoly Tranny Mount, I likely could 
produce in quantity. My first one was was done with a circular saw and drill.
