I've broken 3 before I succeeded.
Kinda broke? Is that like kinda pregnant??
Call a glass shop and get it done. That's what I did last time, on the racecar (after I put the steering wheel through it). Triumph/Diamond, was about $250 installed IIRC. Use the online quote first, actually. There was even a thread on rennlist a while back about prices, but the later '44 windshields are pretty pricey - a 924 (including S, IIRC) only needs the cheaper earlier style.
It's just too cheap to bother DIY.
EDIT - forgot to clarify - use the online quote service, and then schedule an appt. Otherwise the local shop owner will try to rip you off, add $100 or more to the bill 'cause of the P-car thing. At least that's what I experienced locally. F'ers.
