If you go to the Fiero Store page 71 86-88 GT OE style Quarter window. Part number 50395. Those are the style I am going to replace. Also not sure what or who CSRA is? The link one of you sent me I'm not sure which section to follow. Just dont want to screw the job up.
That changes things a whole bunch. In your first post, you said 87SE, not GT. Two totally different quarter windows, but a couple of things are still common in replacing them.
Get yourself a good pair of leather gloves. The windows on the car will probably break during removal. Use a putty knife of about 1 1/2 to 2 inches wide to remove the old windows.
Start by removing the engine vent. Near the window you will find 2 hex head bolts. Remove them. There's also one at the back edge of the vent. Remove that one, too.
There is a square filler button in the very tail end of the quarter window trim piece, just above the trunk seal. Do not try to pry it out. Remove that little phillips head screw, then the square filler button will pull out.
With it removed, grab your putty knife and go back up to where the grill covered the two bolts. Slide the putty knife underneath and against the bottom of the quarter window trim and separate the wide double side tape that acts as an insulator. It sticks to the bottom of the trim piece during factory installation. Now, go to the top front of the quarter window trim piece, near the rear window and insert your fingers behind the front end of it and pull slightly down and out. The trim will begin to come out from under the top of the flying butress. There is probably some of that good old gooey black butyl rubber holding the trim to the body, especially near the front.
When you've worked the trim piece almost out from the front, you'll probably have to turn up the edge of the trunk seal to get the back edge from under it.
With the trim piece removed, at the front of the quarter window and taped to the back side, you'll probably see some mono-filament line. Grab both ends and pull. If you're lucky and they haven''t rotted, they will cut the tape around the perimeter of the window, allowing easier removal. Likely due to age and weather, they have rotted and will break.
If they break, begin working from the inside where the engine vent grill was and insert the putty knife downward between the body and window. Work your way along the window, overlapping what you've just separated, until you've addressed the entire top and bottom of the opening. You won't be able to reach the front.
Now is when you need to don your heavy work gloves because the next step is where the window will break. Grasp the back end of the window and pull it outward. Beside the remaining tape along the top and bottom of the window, there's a vertical strip just rearward of the front wraparound edge, and I believe there's also a vertical strip about midway of the black field.
Once you've removed all the pieces of the old window, you have to thoroughly remove all of the old tape and adhesive from the body before installing the new window.
If you want to come down to the Stone Mountain get together, tomorrow, I'll show you and explain a little better. Information is in the Club News section about the Stone Mountain Cruise.
