Anybody know if the coil springs on the 2002 Montero Sport 2WD are the same as the 4WD model?

My Montero Sport has always had week rear suspension and easily bottoms-out. I want to replace the coil springs with heavier duty ones. All I can find are coils for the 4WD model.

 

Should be the same, I would hit up a boneyard. If you cant find any there then these guys can probably set you up. OME Suspension: Old Man Emu Suspensions and Lift Kits
