How much for the windshield?

According to this: for JUST $100,000 more you get a 959, too.

Hey, aren't you looking for a convertible?

Gerard-- Per the above Yahoo link, the sale includes two windshields - Cabriolet and Speedster versions.

As topGear.com's "For Sale: One-Off Porsche 959 Cabriolet" mentions, they're interchangeable.

IIRC, all 911 Speedster windshields are removable after 4 bolts are loosened; 2 frame mounting points on each side of the windshield.
