Broken anchor bracket

A contractor from Lansing mi says:
purchased the 34" series 770 balance. I do not see a matching clip. It measures 1" wide 1 3/4" long and 9/16" in depth.

Hello,

You may need something like our 15-178 pivot bar but you'll need to remove an undamaged pivot shoe to get accurate dimensions to compare. If the dimensions don't match up, please send a photo of a more intact shoe with accurate dimensions and we will continue researching for you. Thank you!
