Doug, I bought the rollbar from CMC when I bought the "kit" in '88. I have seen them for sale here, but a lot of people also have negative things to say about them. They are described as decorative rollbars, and I agree that they are far from a NASCAR rollbar, or even SCCA; but they may be better than nothing at all...or not. I have never heard of a Speedster rollover where a rollbar of any design was tested. I think two support braces emanating from the top horizontal bar back down to the frame at approx 45 degrees would be a big plus, but then, just about anything can be improved upon. Anyway, with the addition of the lower horizontal bar, it does make a pretty handy shoulder belt mount approximating the way they were intended to be mounted. Unless the area of the backup washer was measured in terms of square feet (greater than one), I would probably question the strength of any seat belt attach point bolted only to fiberglass, rather than a steel floor or frame. Just the rambling thoughts of an old man. Good luck. /john
