Tim,

I have no opinion on roll bars, but I have heard it mentioned on this 
list and forums that classic insurance companies will not insure a car 
with a roll bar.

Again, I have no experience with roll bars so this may be BS.

But, it wouldn't hurt to check with your insurance underwriter first.
