1970s sliding glass door

Hi, older sliding glass door. Wheel assemblies have finally died. It's a rental property with great CSU students, so I need to replace the wheel assemblies in one shot. I've uploaded pictures of the door, can you tell just from these photos what I may need? The door's configuration on the frame (both sides) is 2 holes at the bottom, one hole in the middle, and one hole at the top. This was probably a very common sliding glass door in its day. Also, you can see from from the ultra wide tracks, it used to have an additional storm door. I would be willing to buy a few sets to see what works and return the unused ones. Thanks!
