paul before you install you'll want to put some rubber gasket or spacer material at a couple points on it. after certain mileage the pro plate will creak entering driveways and such due to the design of how it sits against the crossmember at the rear mounting points. mine took several thousand miles to start creaking but we just dropped it and put chair leg pad thingies at a couple points and no more creak.
also be aware the last drips of oil can drip onto the pan itself. after a few oil changes with the pro plate I'm now going to set some manner of shield up there when draining.
if you look at this pic of a pro plate you'll want the rubber material (doesn't need to be thick could even be washers) where you see the rubbing at the bottom of the pic.
