We don't sell a balance in this style with only a 1/2" diameter tube. I recommend checking that just to be safe. The only available options are the 3/8" Series 900 and the 9/16" Series 600

As for the pivot shoe, the best match will depend on size for this, as well. Can you tell me how thick it is?
