I'll post it again: I'd rather do three clutch replacements than one windshield R&R on a B roadster.
Tape looping around it can help, using stout tongue depressors (NOT popcicle sticks) and chopsticks can help curl it out, too. Just DON'T use screwdrivers or other metal implements.
Lining up the four bolts under the dash is a joy as well. You need the hands of a six year old. A "wobbly" socket helps a lot to tighten 'em. The U-joint type.
Usually takes about six months after it's done to forget all the aggro and pain.

EDIT: I see you don't have the dashboard in yet! Good!! Get the windscreen in first, makes the bolts a moot issue.</span>
