Hello, We need six of each kind.

Your top roller assembly looks like our 23-046, except ours comes with an adjusting screw where yours is spring loaded. Our 23-086 comes with a concave nylon ball bearing wheel, but the mounting screws are in alignment instead of off-set like yours. If you use this, you will need to drill new mounting screw holes. Let us know what you think. |
