So I looked through this forum and didn't really get a clear answer and I was wondering if anyone can help me out. I am missing the trim piece in the center of my rear sliding glass. I am brand new to the square body platform and I do not know if this is factory but I am wondering whether or not I need to install an entirely new rear window or if there is a way to replace the missing piece(s). Here is a picture of the truck. If anybody knows where to buy this piece that would be very helpful information to keep my truck dry. Thanks in advance.

Even if that is a factory rear slider, which I don't really know how to identify that, I would think that parts like that would be completely obsolete. Probably the only realistic solution is to install a new aftermarket unit, of your favorite type.

Ya'll are correct. The only way to fix this, Joe is to get a used frame and take the piece out of it or buy a new rear window. There are plenty of them on the market. I believe that maybe in the late '70's GM did offer a sliding window for pickups. It's identified by a heavy frame, polished aluminum or painted black, and the two center windows slide apart. Is that the piece that is missing, the center locking and handles mech.? Heck, contact @AuroraGirl and see if she might have one laying around (literally).

Yes that is the piece that is missing. The windows are a 2 piece that slide out from the middle. I bought a latch in case I find one because I'm not ready to pull the glass yet since it was resealed recently and is in great shape. Sadly in NJ there are next to no squarebody's in any junkyards by me so I'm gonna tape it and hope I find one at some point.

In the meantime, a small strip of clear vinyl protectant like Clear Bra will seal it up nicely and be virtually invisible for probably 20 years.
To find some, I’d suggest searching FB and CL in other areas of the country or anywhere really. There are a lot of guys parting out squares. Several around here locally. Might cost you $50 to have someone take apart and ship, but new window is $200+ plus install.

Yeah I am trying to find junk trucks with the sliding window but to no avail. Mine is definitely not factory because mine looks nothing like that so I have a feeling finding that center piece will be difficult

And a lot of sliders have the same technology.. may have something somewhere and it not be so obvious. Any manufacture indicators on the glass in the corners or part numbers etc anything
what color is the frame
is it a dual pane slider or a single pane
is it tinted
SHOw USSSSS

Also, if you cant find a part, a new slider with modern design and quality tint can be had for not a lot of money, so you may decide to go new. YOu can install it yourself if you have patience some youtube learning and a window!!
some soapy water too helps lol

Show usss

definitely not OE. If you know the seals are perfectly fine all around beside the middle of course, you would be best trying to track parts probably but if you have any sealing or sliding issues, I would just put the effort to a new unit. But definitely not a bad looking slider.
