Please identify the Pivot Lock Shoe and Tube Balance parts that I need

Thanks for posting. I believe recognized the balance system you need will be our 5/8" diameter Series 600 spiral balance with a red tip. Look it over and see what you think. The manufacturer of the pivot shoe has gone out of business, so we will need its width and thickness in order to find the best match. We will also need to see the pivot bar that interacts with it.
