Buying the proper Jet kit

[89gS500_Kirk]

So I am ordering a lunchbox air filter and I know I need to re jet the bike when I do this. I have been searching and I cannot find a kit that has the proper jet setup I am needing. According to the Wiki and what I have read on here I need a 40 Pilot and a 140 Main. Does anyone have a link where I can buy a kit or do I just need to piece the kit together myself from ebay? I am planning on using the stock exhaust for the time being also.
