door rollers for a Riabilt

I am having a really hard time find new door rollers for an older Reliabilt sliding glass door I bought at Lowes maybe 15 years ago. I hired a local glass company who came out with a box of rollers they had on the shelve and did not have anything that matches.Attached are photos but noticed that the starting point on the measures is off by 1 or 2 sixteenths of an inch as it looks like their tape measure is separating between the yellow and silver part there.
