Hello everyone. I'm new to the forum here. This past weekend I purchased a 1950 Buick Special Tourback Sedan. I still have to double check the ID plate if it's a 41 or 41D. However. Other than it mechanically, electrically, and body-wise being in excellent shape; it's a little bit of a basket case. LOTS of stuff to bolt back together. Prior owner stripped it and got it painted, and prior owner to him had engine rebuilt. I just need to re-attach chrome, put the already re-covered rear seat back in, and not a heck of a lot else. As we're inventorying parts however, I'm short a window; front passenger side. I have all other windows with the metal sash channels still attached at the bottom. I've been able to track glass houses down offering either original, NOS, or fresh cut. HOWEVER, I need the sash channel for the bottom of the window in order to remount it in the door! I found a Chevy body manual that lists a part# 10.685. I've ordered a Buick manual, but have been trying to hunt in the meantime until the Buick book shows up. Maybe it's a different part#, but it certainly looked the same. About 2' long, aluminum, with trapezoidal/triangular brackets screwed onto the bottom. Has anyone else been able to track replacements down? I may need more window components too, but I know this piece for sure!! Thanks for any and all help. I know I probably have some duplicate parts as well, so after it's put back together, I may try to list them here. Thanks!
