Note the motor mount rubber bushings  on the PSRU adapter plate.
Great minds work in similar fashion :-)
The motor mount itself is a tubing version of the P51
style. Dave is using some kind of heavy duty aircraft 
starter that really spins the engine over according to 
Tracy. It is mounted on a rear accessory drive plate that 
Jim Mederer of Racing Beat designed for someone else a long 
time ago. This is a good picture of the helicopter planetary
reduction unit. Looks very similar to half a PT6 gear box.

I'll take some more pictures when I go down there.
