Here is an idea I have been kicking around (we will probably use it this year on ours, too).
Take, say, three bolts. Whichever length/size is best for you.
Epoxy their heads to the rotating plate on the window motor (you know, the one with the gear in the middle of it). You could probably do welds, too, but I would be super careful about that. Disassemble the motor before attempting a weld.
drill the appropriate holes in your plate, put it over the bolts, and tighten nuts down.
We are considering this for mounting our stuff on our window motors this year. We considered a straight epoxy, but we wanted to be able to remove the stuff if it gets broken, so we will just do the bolts.
