You don't really need 26.
20 is available new from a dealer and doesn't cost much.

#26 - yeah, my K75S doesn’t have it. Putting the newly acquired belly pan on my K75C - just trying to restore it all to original. (I guess I should buy 2 in that case 😂)
Yes, I did look up all those parts at ascycle in California - the first dealer I found that had part number 15 - “discontinued” by everyone I searched before that. Figured I get the whole lot from them, fasteners and all. Came to about $65 US, plus exchange, shipping, duty and brokerage to Canada. Quickly ads up to over $100 Cdn.

Was hoping someone would have all these bits used at a lesser price.
