No fold door top pivot housing

Hello,

I don't recognize this pivot at first glance. If you could show us photos of where it fits in the track and the pin that fits into this pivot, that would help us confirm if a possible replacement is available. Thank you! 

Unfortunately, we were unable to find a substitute for your pivot bracket. We suggest a new top rail kit with a bottom corner bracket so you won't need to drill holes along your wood floor. Look over our various track kit sizes, ranging from 23-504 to 23-507, and see what you think.
