Need help with this bracket, can't seem to find the correct one at any of the hardware stores. it looks like a simple bracket. The house was built in 1956 if this helps. I also added some pics of the back of the closet door in case that helps with the door manufacturer. There is a plastic peg that is built into the L bracket that fits in the holes on the top and bottom tracks.

I see some similarities between your part and our 23-020 bottom guide bracket. Make comparisons between both parts to see if this could be a match for you.
