i'm pretty sure the bolt holes won't line up. i was about to put an edge skid in my 99 indy 500 (evolved chassis) and the bolt holes didn't line up so i threw that idea out the door. if he's looking for a taller look, you could always get rear suspension hangers that raise the suspension. because the suspension in his xc 700 isn't that bad, it just doesn't have much clearance.
