http://www.ebay.com/itm/110986901961?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649This is the ebay auction for the rear glass set for the 49-51 Hardtops. It appears to be tinted and has one chip as seen in the photo. Center section. This piece in my opinion can be glued back into place with no loss in quality of the otherwise perfect 3 piece set.
As mentioned in the auction, I may not be successful in getting this out. Obviously $200 is way to much to ask for this UNOBTAINIUM part. So, how about anybody need this for FREE subject to my successful/unsuccessful removal.
Let me know by PM. I'll even pay shipping so it doesn't cost any money to you.
