Vent window changeover to later model assy's

[RPOZ11]

Hi All!
I did the vent window changeover today on my 84 1/2 ton.
I used the later model 87-91 issue assemblies having the thicker gaskets!
The thicker gaskets work well!
They fit they same as the earlier versions.
The only thing I saw different was that the middle securing screw on the door's 45* pillar was not desigened into the newer ones; so you will not need the extra screw and angle washer.
However, my screws were very tight, or what I call : Metal Seized.
I had to get a BBQ propane bottle with the Sears Craftsman Torch attatchment and heat up those pesky screws.
Be careful not to try to remove them if they are too tight as you might strip out the X on the head of the screws!!!!
You will need every bit of that X to get those screws out!!!
