Honestly, there are plenty of Q45s in salvage yards now - and this is a part I would probably feel comfortable buying used... Might check
http://www.car-part.com to see if any are available locally. I know the windshield tint band at the top varies by car color, but to my knowledge, the others are all the same.
Check
http://www.car-part.com for used. Make sure to limit your search to 94-96 Q45s. The 90-93 had thinner glass... part of the '94 mid-series update.
Oh, and as Brian said, be sure to get the FSM. It will tell you a lot about removal and installation. You'll need to find some freeware (google for it) to decompress the .rar file that you download at

Good luck!
