I'm in the process in converting all my hardware over to stainless steel and I thought I'd share some of my efforts. I WAS going to try and sell Stainless kits but I just don't have the time.
Anyway, here's a spreadsheet listing the hardware, prices and links for a 1976 CB750K frame. The hardware SHOULD be the same for '70-76 but you should double check just in case.
Each nut, bolt and washer has a reference number, if you click the reference number a link will pop up to the left of the applicable cell. If you then click that link, a reference diagram will open in a new browser window indicating where that specific piece of hardware goes. Also, I have listed the vendor's P/N that I used to obtain the hardware. Just like the reference numbers, the vendor's P/N is linked to their websites where you can order online.
Please note that this hardware is NOT exact JIC replacement hardware. If you're restoring your bike to 100% exact factory OEM specifications, then this thread may not be for you. I have also taken the liberty to replace some of the standard nuts with Nylon Locking Nuts where I felt they would work best. These areas include motor mounts, steering components and other parts that experience vibration or would benefit from a locking type nut.
Anyways...here you go.

Since I'm swapping my forks out to a GL1000 style, here's the hardware list for 1975 GL1000 Triple Trees:
http://spreadsheets.google.com/ccc?key=0AsJW59Xg-wu7dEFrUkhWd2FMRWRKQ01NZk5qd0FCZ3c&hl=enGL1000 NOTE: The GL1000 upper tripple tree has recesses machined into them to that the bolt heads are countersunk. Likewise, the stock Honda "upper triple tree bolts" have a smaller bolt head (JIC) to them so if you use a non-JIC bolt won't fit into the recesses. That is why I have a socket style bolt listed on the spreadsheet instead. You may also notice that I don't have the handlebar mounting hardware listed. I'm using Tomaselli clip-ons so I won't be needing those clamps.
Rear Shock Hardware:

I'm working on more of these spread sheets and will post them as I go. I only feel confortable posting the spreadsheets after I've tried each bolt and can guarantee that they'll work.
Enjoy.
