tube balances & corresponding pivot bar & shoe

I have multiple tube balances to replace and there are also a few broken pivot bars and shoes. I found the tube balances on your site (series 600); however, I cannot find the bars or shoes. I was not able to remove a shoe to measure it. If I locate the correct cam I will merely order some of every size to ensure I have a size that works. I also could not find the reversible pivot bar on your site, but I have sourced them elsewhere. Any help identifying and sourcing this shoe would be appreciated.
