Replacement Knob screws for wake tower.

[Captain_Ron65]

I need to replace 3 knob screws on my wake tower. I found them on Yamaha Sports Plaza for $50 each plus shipping. Has anyone found a cheaper place for parts? Also, the reason I have to replace them is because I could not remove them so I could lower the tower so I had cut off the knob and grind flat spots into the bolt to get them out. Any recommendations on how to lubricate them once I have the new replacements to prevent this issue in the future?

I usually take the part number and look on Ebay, if only for a sanity check.

I used this on my 2012 AR240.
