Outer Limits 4x4 Board

hi everyone. just picked up my 1990 maverick. drives really well. the truck is definately lifted in the rear, not sure about the front. tyres are 31x10.5 r15lt. does anoyone know what the height should be from the top of the tyre to the bottom of the guard. the rear gap is 230mm, and the front is 190mm. thanks.

bad way to measure as all tyres are diff and guards can be chopped, should have about mm between bumpstop and the plate it touches.
