Bought the tinted acrylic (on-line. Made a template tracing the top of the old windshield from poster-board, then cut out the lexan shape. Built a little bending thingamajig with plywood + some stainless screws, an aluminum u-channel, and some 20 gauge Ni-Chrome wire (and one spring to hold it tight when the wire sags during heating). Old car battery charger provided the DC power output.
Anyway, I'm pleased with the outcome. Main lesson was to be a little more careful with the scalpel when cutting the protective paper (scratched a bit), and believe the guy who said he had to wait 11 minutes for the acrylic to heat over the wire before trying to bend it. If you rush the bending it will crack, and if you pull out your heat gun to spead it up, it will form small bubbles in the plastic. Ask me how I know.

Here are some photos. If anyone wants to try it, I'll happily share my bending jig.
