SAS steering box plate

i plan on doing the sas next year or so, so im planning ahead... right now im making a bumper and i'll be making plates that go along the frame rails to mount it and the winch to. my problem is i know there is a plate that goes there for the swap to mount the steering box to. can anybody give me dimensions on it, a position it gets mounted to, or a thickness for that plate so i dont have to cut my bumper up later on when i do the swap? i attached a picture, the plate is outlined in red, my mounting plates (for the bumper) will probably go from the front of the frame back past the rad/cab mount up to the crossmember. ill be cutting the rad/cab mounts off and welding them back to the plate minus the thickness of my plate.

thanks guys,
-Nate

p.s. i have a 2001 excab tacoma
