Help with vent window
« on: December 01, 2023, 09:15:53 AM »
I bought my son a 77 bonanza and we are slowly working on a few things. First up was driver side door.  I bought everything to replace the vent window and door glass and when I went to change the vent window I learned I actually have a 81-87 vent window assembly (I think).

The glass is thinner, the vent glass is 15 3/4Ē tall. The door glass for the 77 was a direct match and fit.

My question is: does the vent window division bar change for the 77 to 81? I ask because the frame I bought had a tab above the spring
and there was no way I couldíve put it into the assembly even if the glass fit.

I canít seem to find a 77 division bar or vent window assembly anywhere online anyway.  I may just buy the 81-87 to get it closed up for now.  Do I need the 1 pc weather strip or the 2?

IIRC they are incompatible. Are kits for '77 not available?

I can find the frame, but canít seem to find the division bar or other parts of the assembly that attach to the truck.

I might have to do some junkyard hunting for it.

Division bar is the same, the weatherstripping is different for thicker vs thinner glass.

Bunch of complied info for the door components here: http://forum.73-87chevytrucks.com/smforum/index.php?topic=14625.0
