thanks.

Yes, no shims under the rear stop.
The washer under the front screw locks the front end completely. That stops the front of the bar moving, the only flex will be in the part itself.. You could of course just use normal M3 x 10mm screws to hold the whole thing down. That would be uber stiff.
