Do you just have a cover plate over where they would mount now? Can you snap a pic of what is there now? Based on whats in my car, Im not sure how you could not have visors without some sort of gap plate or similar?One thing to keep in mind is that not all brackets are interchangeable. I know that convertible brackets are unique, and I think that crowns are as well, but not sure on interchangeability.....I do know that brackets and Im pretty sure padded visors are now avail repro as well, although the visors are only avail in white and need to be dyed.
