The problem with interfering with the travel of slide is that it won't properly align to the side of the outside wall if the travel is restricted at the end of the retraction. Does you slide take the tension off the rollers at the end of the travel in? The service manager at my dealership said that they have some teflon shims that might fit the need for me. I am wondering if the sides might be made a little longer also, since it seems to travel in and out just fine with the bottom about one inch down from where it belongs.
