The Best Top will work, but flap around a bit. I have the same problem on my 89 I built a roll cage using a 94 roll bar. My cage spreader bars are inward of the stock spreaders, so When I take off the stock spreader bars in the summer so that I can drop the window, then the bikini top side straps cant reach the roll cage bars. it still works though, it just flaps a little,(not to bad because you still tighten both sides and the middle rear ward with the straps provided.
