Ok....My 85 SE V6 had the paint start dying in 1998....It had been parked outside it's whole life....The paint started to crack into tiny little pieces...I found out that a good paint job would cost $2000 (Yikes!) so I started looking in the junk yards and found a factory-paint hood and roof....and a GT rear clip. When I started taking the quarter windows off, one was already damaged at the front, and the other one cracked when I tried to remove it and the body clip at the same time (That stud!)
I had always liked the look of the 1975-1980 Monza "B" pillar vents, so I decided to copy the decklid grills on the Fiero GT- and failed miserably! I tried to cut that shape into plexi that I figured I could then heat and curve...Just could not pull it off- So I finally decided to just go with a flat piece.
I cut some 1/8"aluminum and then ran it thru a roller to give it the curve..I had to have a co-worker with some muscle turn the handle...I would suggest using a hydraulic roller or press instead.....I carved and curved a front piece, then had a friend weld it on and shaped it to create a nice curve at the leading edge.....I made three tabs that catch on the body- 2 at "D" and 1 at "C"...It actually twisted on and would probably stay, but I felt safer securing it with a countersunk screw into one of those nylon expando nuts ("B")....Then, covered the screw-head with a G6 trunk emblem. I painted them the same graphite metallic that I painted the wheel centers.
The quarter windows were originally held on with thick tape strips- The quarter windows as original are flush with the body, but the front side windows are recessed.....This seemed to lack continuity, so I bonded the windows on with black RTV, which hid some of the scratches in the black-out rim of the glass, and also moved the quarters in approx' 1/8".....not exactly matching the front glass...but closer...As you can see, I also worried about the RTV some day failing, so I used some more of those nylon expando nuts and screws with finish washers ("A") as a "Fail-safe" to keep the windows on the car even if the RTV died.
The idea here is that the gray "B" pillar fools the eye into thinking that it really is the thinner >B< pillar, while the blacked out glass that hides the real structural pillar looks like part of the window....This makes the car look a little more graceful with a thinner "B" pillar.....
Making them out of aluminum was easier for me, especially with access to metal working tools, and a welder friend (Who will not let me pay him!)...If there was interest, these could be made out of Fiberglass much easier.
