gray area(MII in a chevy truck-who knew?). as long as it is plumb to all measurements in relation to the ground. use a universal kit to place the framerails higher in the cradle. you also may need to trim the rail for the upper spring/a-arm support.(usually not on a chevy)but it needs to be boxed anyway where you install the crossmember, and you will retain the strength needed.
