I don't know, I.ve tried em both ways. My 88 GL Turbo, 3" lift, 5 bolt XT & Leg. mods, is mostly on hgwy. To much sway to suit me, I put on the XT bar in fr. & plan to try the XT rear. I'm workin' on quick release Fr. bar links, like the big boy 4X4s use, just smaller scale. Thanks for the chatter guys. S.
