Attached are (2) pics. I a trying to determine if the part i need is 1/2" thick or 17/32" . The 'face' of the 1/2" looks like the piece I have with (2) small circles and rectangular cutouts in the plastic. The sides that slide up and down in the track.
The website pic of the 17/32" shoe has no holes but does have a blue brake. Not sure which i need?
Thanks for your help.
Glen
