1981 KZ550 Carb Jet replacements

Hey everyone
My main and pilot jets are both frozen up so I am unable to read the sizes. I've tried wd-40 and kroil and they won't seem to budge so I've decided to just buy new jets. I'm looking for the stock 81 Kz550 LTD jets but I can't find them anywhere. I've tried Z1, Jetsrus.com and ebay and have come up empty. Does anyone know where I can find the stock jets for these TK-22 carbs?
Thanks

Take a look near the bottom of the following link. It has links to some sites that offer kits, etc. that may be helpful. Ed

Most of the rebuild kits come with stock jets.

You can also use small-head Keihin jets, but the numbers may not be exactly the same. I can't remember if you want slightly highe or lower numbers on the Keihin main jets.

Thanks guys.
I'm seeing a lot of mikuni and keihen jets sold as individual parts. Do all jets fit all carbs or will some not screw in correctly?

Some jets have different threads. I only know of the small Keihin mains that work. Also, Dynojet makes some that work, but I don't know if you can get them separately. Here's what to look for:
