For the GS500F - laminar lip in good condition, will need to get some more stick-on pieces. US$84 new, selling $25.
Manual in as-new condition. $25.
Prefer local transaction, will look into posting if necessary and add net cost to purchase price.
Correction - I have found the stick-on pads for the laminar lip so it is complete. It made a huge difference for me on freeways, they went from being a real chore to something I could do for hours in a day as necessary.
Is this still available? I'm interested if so...sent you a PM, let me know.
