WANTED 71 yorker rear window channel

Hey guys,

My rear window leaks into the trunk. Discovered its rusted the channel where the window rests at the bottom. Does anyone have a parts car with good/decent channels they can cut and ship? I'd need about 6-8" in each direction from the corner of the channel (both corners leak). I can post pix of what i'm dealing with when I get home tonight.

I'm not sure what other bodies will fit for my Yorker, as I'm new to the C body scene. If anyone has done this repair, I'd appreciate some pointers (yes I have a MIG).
Thanks
-Trav
