Yamaha PS 55 Replacement Slider

Hi there!

I have a Yamaha PS 55 that is missing a few sliders. The standard slider is out of stock and I was wondering what a good alternative might be! Would this one fit: Part #5320 (silver, Roland). Any suggestions would be great!

Also curious if any one has tips for cleaning scuffs and scratches on casing without damaging paint. Thanks in advance!
