Hijack
I have Yakima racks back home that have been used on both a 1994 Caravan and a 1988 FSB. Both cars have the gutters above the windows that the rack clamps onto. To be honest, I think it will work on an EB since the hardtop looks like it has the exact same gutter setup. Haven't taken my rig back home yet to test but I'm confident it will work. Just order one with the clamps on the end of the bar and cut the bar down to what you want.
