Sliding glass door rollers

I think we can help with this roller, but I need a bit more information before I make a recommendation. First, can you show me a clear picture of the back end? I want to see how the screw holes are arranged. Can you also measure the height and thickness of the housing and tell me what you get? I would like you to measure and then write down what you get for me. A picture of a tape measure isn't always clear for us, so having the hard number would be more helpful.
