You're welcome! I think you'll find your best fit at Newark, they seem to have the most thorough selection.

I'm glad to see you're using encoders for the swerve drive. Lots less to worry about than potentiomers. The only thing is you might want to search for an absolute encoder so the robot can figure out the orientation of the wheels. Usually that means that it's a triple encoder instead of a double; the third disk will have one notch in it to mark each revolution. That notch always occurs at the same angle so you can use that to initalize your wheels to a certain angle every time your robot turns on.
