    Why not! It's not like you are going to ruin a big-dollar part.

    Try shaving the rear towers down as much as possible without touching the pump. You might need to clearance the ribs inside the plate.

    Expect it to be much bouncier.

    Towers you mean on the hull side where the bolts go through to get a better angle. I have three washers on front none on back I swear that gave me at least 1mph..

    Yep, grind the rear mounts down for more angle. You can shim the front down but don't let the angled sides of the plate be lower than the angled sides of the pump shoe, it's needs to be atleast 20-30 thousandths higher.

    You want to grind enough and still slip a peice of paper between the pump and plate.
    If you are unsure, Jim's Performance specializes in rideplates as well.
