I mounted the rudder pedal slide and drilled the front mount to the slide. I had some difficulty putting the rudder pedals on the slide: there were burrs on the inside of the rudder pedal bushings. I spend some time with the Dremmel tool smoothing out the part to allow it slide smoothly on the crossbar.
I also had trouble finding the F-874 bushings. I eventually found them in the bushing parts bin.
