So the problem you run into with 1990s cars that next to no one wants is, well, just that. Parts are near impossible to find at times due to demand not existing. Tried to find replacement pieces for the shifter on my 1990 Geo Prizm hatch (see pics, it wasn't even optional at this point it was so bad), and had no luck. Taped together and measured out the pieces I could piece together, as well as went through a couple iterations, and VOILA!
Being a part going into a hot car, be sure to print these in a higher temp filament like Nylon, PC, ASA, or at least PETG. Also would recommend printing on a textured bed sheet with both parts FACE DOWN, to get that vinyl looking effect you see in my pictures. To start with, I'd recommend using a .25 nozzle for max detail, though .4 should still be fine. Start with black, and set your printer to do a filament change at the layer where it starts filling in the letters on the shift indicator and swap your filament out to white to get the white letters that light can shine through. You can print both parts at once, and the remainder of the shift dust cover can be white without the white being visible on it. I used a 0.5mm PET sheet of plexiglass to keep the indicator free of debris, and used the printed part to trace on the plexi and cut it out by making multiple passes with a sharp blade on a box cutting knife. To make the flag visible on the dust boot, I'd recommend using a phosphorescent enamel paint to paint the flag to give it that extra pop. In the pictures I have posted you can see the paint I used present with all the parts laid out. Assembled picture was a test fit where I hadn't painted the flag yet.
