4 Point Mounts?

[DelawareDave]

How thick are the front and rear 4 point motor plates? Aluminum vs. stainless? I may go to a 4 point mount and rail set-up.

I believe that they are 3/8 but not sure. I can measure when I get home. One of these guys will probably post it before I get off work though;)

They should be 3/8". some make them out of 1/4" material, but with any HP they will flex and let the motor go back and jam the driveline into the pump thrust bearing and wipe out your engine crankshaft thrust bearing in time.
