No on the bimini top.
I have an older Beck top that I got on Spyderclub.com. It came to me with a windshield header, hoops and side curtains, but no articulating frame. So I fabricated one.
I used 1/2" x 3/16" steel IIRC. I also used some 6mm x 1.0 bolts, some conventional rivets and some nylon washers at the pivots. I had to weld some tabs to the hoops. I also had to drill and tap the header to attach the frame. It works just like the newer Beck tops.
The top is fitted, I just need to have it cut out for my headrest fairing and install a few snaps on the deck/clamshell.
I have the Beck side curtains as well, but wanted to make plexi for bigger side visibility. I purchased Troy's cruisin' windows for the hardware and will eventually cut my own windows. Spyder doors are a lot shorter than Speedsters.
