I'm guessing the figure's higher than your friend wants to pay going through a parts vendor (LMC or who ever).
You may shoot an email to this guy:
spltwindow@msn.com
He may have one. He gets a lot of stuff from swap meets to sell. I can't vouch for him but, he seems to be a nice fellow. I've emailed back and forth to him a few times.His name is Robert and he's got a website at:

Hope this helps,
Jon

"I am for doing good to the poor, but I differ in opinion of the means. I think the best way of doing good to the poor, is not making them easy in poverty, but leading or driving them out of it."
Benjamin Franklin, On the Price of Corn and Management of the Poor, November 1776
