Check the tops at www.cabrioworld.com - I had one of those on my 92 B&T. Nice top, especially for the $$$. I got the zip down rear window, which was just like the OEM top.
They aren't too bad to install yourself either... I didn't do the B&T but I did put a used top on the 92 blue. Be sure to pick up a rivet gun.
If you haven't checked your rain rail, I'd suggest just going ahead and getting a new one of those too.
