I did not use sliders instead I got some cheap BMX pegs and drilled them out to fit. I put them on the frame mount bolts in place of the washers and they worked really well when some kids pushed my bike over while I was at work.
They would not work as well for a crash at speed but I seem to knock my bikes over in the driveway the most anyway. They also make good highway pegs.
Cheap steel BMX pegs seem better than the higher quality and lighter aluminium ones ,at least for my purpose.
