Del Mar door roller

A home owner from Mahe, Seychelles says:
I am looking for 3 pairs of roller wheel on my sliding door. On the roller it has DEL MAR ENG. LONG BEACH CAL PAT3,670,357.

Mine has plastic roller ball bearing wheels.

I have attached a few pics the outer cover has a flap that has a hole for a screw to hold the roller wheel into place. Also the outer cover has four dimples two on each top.

The track that to roller wheels slides on is aluminum, is it that I have to use plastic wheels?

Please help me to find 6 or three pairs.

We have located a replacement version of this roller with a nylon wheel. Take a look at our 81-256 which now has an option between a steel wheel and a nylon wheel.
