I was not very comfortable with bolting the engine and transmission solid in the frame..so I modified the front engine mount and fabricated a factory style mount for both the engine the transmission. This should help to isolate some of the vibration. The carburetors do not like solid mounts in a 911..so heeding the advice from Rick Parr at PMO..I updated the mounts..I hope the new system will help. Hopefully the new mounts will also eliminate stress cracks. I also made a few tools to ease in installing the motor.
