Jupp, I think the Nippon Denso (black) window motor had the 9-tooth gear and could be fitted with the black plastic coupler that came in the kit. The Jideco motors had the 8-tooth gear (correct me if i'm wrong).
There is no sprocket for the Jideco, at least not that I know of. Some teams get around this buy finding the car that the window motor went into and just pulling out the arm assembly (if you can find the car in a local scrapyard) or just ordering the window assembly from a dealer, which can get sort of expensive.
The other option is to cut your own gear coupler. For the Nippon Denso motor, teams used the CAD files from the
FIRST CAD Library (it is under the Mechanical part's link) and use a CNC mill, or any appropriate cutting device, to make a nice cut-out.
For the Jideco, I think someone on CD made a CAD rendering of the cut-out, not sure.
If you don't have access to anything fancy, you could just cut out something close to the gear pattern, and just epoxy the two together -- sort of the poor man's way. I'm sure there's more better ways to do it.
Don't forget about the van door and globe motors, they have shafts instead of a gear pattern, although the van door has a metric shaft, and some of the van doors that were shipped out were funny.
And like what Arefin mentioned, I think you meant window motors. I sort of chuckled when I read windshield motors, I want my car to have a windshield that can go up and down!
Hope this helps.
Edit: Fixed, haha
