2001 Patio Door Wheel Sets, Track, and Seal Channel

The door was installed in 2001. The rollers sets are identified With "Truth" and 31761A. and 1980 and 1982 US and Can Patent numbers. A great deal of force is required to move the door. The wheel sets have a horizontal Phillips or slot head, but turning the fastener seems to just rotate the wheel sets on a horizontal axis, rather than raise or lower the wheels into the door. Overall length of the portion that insets into the door is 118.2 mm. OA width is 18 mm and height is 31.6 mm. The wheel sets fit in a "seal channel"with "felt" that includes a 16.3 mm wide metal channel that is 14.3 mm deep. The channel is 47.5 inches long. The track the rollers ride on is 6 mm wide and 82 inches long. After cleaning everything, the front door rollers scored the roller track. I am interested in a compatible wheel set that would allow for vertical door adjustment. I will also need a replacement / overlay for the damaged track. And a replacement seal channel if available Thanks for your help, Chris.

Thanks for your quick reply Bob! The part checks out. I will place my order.
