I don't know if I screwed something up or if the donor vent frame was bent. I pulled the vent window from a wrecked 84. Seemed OK after powdercoat and reassembly, but now in the truck I have an 1/8" gap. it isn't closed all the way in the picture though, because the latch doesn't work. If I push the window in, like it would be if it were latched, it goes down to around 1/32" and I can still see daylight.

Also, brand new OER (classic industries) latches, as soon as I try to lock the vent, the latch handle spins off in my hand. The roll pin just pushes out of the groove. It's hard to tell but you can see the shiny spot where the roll pin slid over the post.

What am I doing wrong? PICTURES

Just a note for some people on this issue. I had the same problem after rebuilding my vent windows. Couldn't figure out where the gap was coming from with all the seals sitting nice and the pivot rivet installed. I called precision (I used their seals) and spoke to someone in their vent window rebuild group. He told me that gaps like that are not uncommon and to fix it just pry on the window frame until it closes the gap. Keep in mind that you will need to move it beyond where it touches the seal due to the elasticity of the frame. It was scary to do after just rebuilding them, but I did eliminate the gap and now it looks like it seals fully. Haven't been on the road yet with these windows, but all seems good so far.

There are 2 styles of wetherstrip for the later vent window styles, one and 2piece and they don't interchange.

Have you used the right plastic washer for the latches? The older style glass is thicker.
the type is correct, they were originally 2 piece and i used replacement precision 2 piece.

on the latch washer, i'm not sure. There were extra pieces in the bag with no instructions and I didn't have one to reference. I'll check the washers.

If that's all it takes, maybe I tweaked them getting it in. i did have to pry it over pretty good to get it in the door correctly. These are precision seals as well.

so pull it out and bend it around until it seals?

You mean the angled portion of the wing window frame? Like before installing them into the door?

I pried primarily on the part of the frame that holds the glass. The gap seems to originate from a tweaked pivot joint. The little arm that holds the pivot rivet translates into a lot of movement in the window location if it gets tweaked. The goal if you have a gap is to try and tweak that little arm in the direction you need it to seal up the window. It will take some trial and error. I did it with the window fully installed in the door and just used my hands and body weight, no tools.

Shortarms, did you take frames apart?
