Window Crank Splines?

Dunno, to be honest.
All I know is that when I looked through the package, that was what they had in them, that 6-adapter set, and they looked just like those. Maybe he bought the wrong ones? Truly have no idea. I think at this point I'm just going to pick them up from him the next time I'm over there and try them on the car.
If they don't work, I'm only out $10...
