bet most of ya'll haven't even seen one rust here. but it's on the outside of the truck, right under the back glass under the weatherstripping. theres a few little spots bubbling up under the paint. all i need to know is how can you get the back glass out. and can you offer any tips on how to fix it. btw it's an 87 1/2 ton 2wd short bed Silverado.
-
I cut mine out with a razor knife. I plan on replacing the gasket with a new one when I have it reinstalled. I fixed some spots on my front glass frame by using a air die grinder and sanding the rust away. I was lucky, it wasn't rusted all the way through.
-
The weather stripping should have a locking strip if you pull it out you can push the glass, easy to start the window out or if you can get to the rust by moving the weatherstrip out of the way without taking the glass out you can run a nylon cord or small rope in between the stripping and the cab to get access to it.
-
baseball bat, sledge hammer, or a trim stick, or mechanics wire, or rope. Either way get it warm and use some glass cleaner to lube up the seal

87swb, The back glass comes out fairly easy. Take a fiber stick,plastic putty knife, ect. Run around the inside & outside of the rubber where it meets the body to "break loose the seal" . Start in one of the lower corners, roll up 3" or 4" of the lip on the inside on the bottom (if you can get a buddy to help it can be a little easier) & roll up 3" or 4" going up one side, push firmly, but not like a gorilla & work along the bottom, side, bottom, side, getting the inside lip to slide over the metal, once you have the one side loose to the top your as good as done. Now putting it back in, the easiest way is with a small rope or cord, wrap it around the rubber (down in the groove where the metal will go) overlapping the ends several inches, do the overlap on the bottom of the window, apply some dish soap in the groove over the rope. Again it's best with a friend, set the bottom on the pinchweld, have a friend push down & slightly in, start pulling the rope out toward you going around the window from the inside, down & in, down & in, once you've cleared the top corners your all set. Lightly bang on the glass around the edge to fully seat it. That's all, Once you do one you will think "boy that was easy". Good Luck, Lorne

I use a pry bar with a broad end. I push the rubber from the inside out up and over the pinch weld. I go along the bottom and up both sides part way. The I go to the outside and pull out, &down on the glass, & the rubber.
-
ok so the main thing is to take that locking strip out and push the window out on either side. ya'll make it sound so easy. that glass don't take much of a push??? thanks for the replies
-
There won't be a locking strip in the back glass. Just pry one corner on the inside rubber down and push, it will come out with some pressure. I usually have someone helping me so it want fall out...
-
well so much for that, i just shattered the thing trying to get it out. i was prying on the bottom left corner and finally it just shattered. you have to put pressure on it but what's to stop that glass from shattering when you got your hands all over it. let that happen and it'll be nasty. i guess i'll take it to get a solid back glass in it instead of that sliding one but i still got to repair the rust and i'm sure the glass shop won't do that >:( :( :'(
-
If you want the solid back glass, disregard this, but if you want the sliding back glass, go check the junk yards..you can usually snag a sliding back glass for like $20..many will have one they've already removed.
-
i may look into that. well i just got the rest of it out. and the rust is way worse than i thought it was, its bubbled up pretty bad and theres a fewholes too, about the size of an eraser on a pencil. any ideas how to fix this. i don't get it i thought the 81-87s didn't rust.
-
Any metal body truck will rust in any of the salt states. Rust free '73-87 trucks in salt states are very rare.
The best way to fix those holes is probably going to be brazing or lead.
-
i don't get it i thought the 81-87s didn't rust.
I had a dream similar to that! :)
-
For reference I don't pry on the glass. I just lip the gasket over on the bottom or top corner and put pressure on the glass while I roll the gasket out. I have the original slider that came out of my 87 that I will sell for $35 + shipping, if you want it...

Just curious not trying to start anything by any means but I have an 85 that has the chrome locking strip in a sliding back glass I didn't mean to mislead by saying to remove it but when he stated it was a siverado I assumed it would have one. My bad.
-
i did take a strip out on the outside. there were two pieces. i'm pretty sure it was a locking strip. i'm not worried about the glass, never was, i'm really not now that it's shattered.
i'm worried about the rust on the cab. it's rotted pretty bad and there's a few holes. it wouldn't be so bad if it was a fender or something you can replace fairly cheap and can bolt on. this is the cab, the integrity of the truck is ruint now >:( and plus where the rust is, they don't make a replacement cutout for that part of the cab. it's all down the pinch weld on the bottom wide part. i don't know what caused it to rust here. it will be expensive to fix this , if it can even be fixed. well thanks for listening.
-
Naaa id rather do that then replace a rocker..All u need is some new metal and a mig and some body hammers and dolley....Take off the old rust weld in the holes...If its to bad..Make a patch panel ...u can bend metal over a 2x4 or use a vise...
-
87swb, Can you post photos of the rust? We will have a better idea of suggestions by looking at it. Not to pick on ya' , I don't think anybody that has removed a back window thought you would say you broke yours trying to remove it. I'm a little concerned about suggesting a open flame or something around your truck, the way your luck is going I'm afraid your next post might start like: "well my eyebrows are singed & you can figure the rest for yourself" Will try to help, photos if you can.

If you can find one at a junkyard you may be able to cut out a good section and weld it in just take as much of the area as possible to much from the doner won't hurt just trim to what you need. Piece of cake.
-
yea and so u keep ur eyebrows use a welding blanket or even better maybe some thick cardbord taped to the inside would be better...Im not to sure on how u would prevent a fire...That close to the interior with no shield...
-
i don't know how to post pics. you'll just have to use your imagination. all it is is rust on the bottom of the outside of the back glass cutout, right below that pinch weld. i'm gonna lget it looked at. i like the idea of cutting out that section out of a donor truck but if i hired someone, which i'll have to, the labor expenses would go thru the roof by the time he cuts and welds all of that and smooths it up and primers it and you would need to paint it. that's another thing, you can't repair it without repainting the whole truck. as you can see in my avatar the paint is really good on it, not very old and it's two tone, and 2 tone paint jobs are the highest. guess i'll have to ride primer :-\

If you have a picture on you computer, check this post on how to upload it.

BTW, I missed the Silverado part....

I know that finding your pride and joy has rust and it's going to be seriuos work to repair is heartbreaking, but don't despare. The key thing is if you don't fix it now, you won't have a truck to fix later. The investment know is worth it. And as for as the repaint, because of the paints scheme, repainting should only require painting the cap. The cap( back top half of cab around window and roof) is usually paonted one color (grey in your case, right?) then the top half down to the body ridge is red, from the ridge to the last quarter is grey, then red again. I may have gotten is wrong, but all of mine have had this setup, and it should not cost much to repaint that little bit. It will increase in value if repaired, but decrease to nothing if not. Hang in there and don't get discouraged, it will be ok. On the back glass, if you are near west texas,how many do you want???
-
well basically it its all silver with a red stripe going around it. i've already found a back glass. thank you anyway. i'm gettin it looked at tomorrow.
-
OK I see it know, but the pinstripe and the top of the windshield and along the gutter can be used for a breaking point to blend the new paint too. most body shops can do this without flinching. Love the color scheme, beautiful truck
