Bronco89XLT, I think the quality of that soft top is very godd. I have tlked to a few folks that have that version, and it is durable as well as leakproof. HTe blindspot along the sides is an issue, but can be overcome somewhat with the side-mirrors like posted. I have a Skyler fastback top for my 84 Bronco, and the Kayline fastbaqck top for my 86 Bronco. I prefer the Skyler top for it's mounting brackets and Velcro, but the Kaylinr or Soft-tops style that use snaps is O.K. You may find that the snaps can rip out after awhile and need replacing.
I also have the S&W 10-pt rollcage kit in my 84 Bronco, and can see your concern about the rear support braces for the cage interfereing with the softtop. My solution is to modify the cage with removeable clamping collars, so that I can use the Skyler top while not racing. The Softtops version or a safari-style top that looks like a direct replacement for the factory hardtop is the best solution for a permanent /full cage in the rear of the Bronco.
