WTB: Bonnet tire mounting clamps/cams

Hi, All:

I'm in need of two bonnet tire mounting clamps/securing cams (something like RN Part #RNB943) for my Series III SWB. I've got the tire mounting base plate and lock post, and I can buy the securing bolts from RN, but I can't seem to find the clamps/securing cams needed anywhere. Even UK eBay has come up with only complete mounting assemblies, not the clamps alone.

Anyone have an extra pair they'd like to sell?

Many thanks in advance.

Bo

Are these things unobtainable? :-(

Surely somebody out there no longer wants a dirty, stinky wheel stuck on their beautiful bonnet, and needs to sell their clamps/cams? Anybody? :-)

I have two in good condition. If you send email addy I'll forward you a few pics.
