Long story short I have a 74 k10 that i have been restoring for the past 3 years and I am nearing the end. The 74 doors were completely shot and were abandoned for the junk yard. I picked up a set of 81 doors that were in good shape at a truck show. Everything is painted and mounted and I am to the point of trying to re-build the vent windows. Yes I have searched and read many posts on here about the vent windows and this is not a question on how to rebuild them or install the rivets.
The 81 doors came with the vent windows and when I was disassembling them I snapped the post off of the frame that holds the glass. At the time I compared the glass frames from the original 74 vent windows and did not see any differences so i thought well hey i can use this one (since i don't think you can purchase them anymore)
Boy was i wrong. After reading this post from the tech section http://forum.73-87chevytrucks.com/smforum/index.php?topic=27075.0 I noticed that the glass frame portions from the 74 and 81 are opposite. The post on the glass frame that comes up to meet the mount that the rivet gets installed into on the 85 comes down and bends out while on the 74 it comes up and bends out. A quick test fit looks like it will be close to the same but i cant tell without taking the time to put it all together.
Does anyone know if this will work using the glass frame from a 74 in an 81 vent frame? Also it seems like from the post in the tech section that I should be using the 2 piece seals. Does anyone know if they will work with the 74 glass frame?
Worst case does anyone know if I can purchase the glass frame piece for an 81 frame? I know places like and others do not offer them so any help would be appreciated as i would prefer to just get the correct glass frame if i can and get these dang things finished...
Hind sight I wish I would have converted to full glass windows before purchasing all of these pieces to rebuild the vent windows.
Thanks

I have welded the post back onto the bottom of the window frame before. Just tack it, let it cool, tack it again. Any more heat than that will break the glass.

So just use everything for the 81 doors and you will be fine.
