Bedroom slide bearings

[Redlionman]

Looking for a place to find bearings for the beedroom slide on my 2005 HR 40plq. I think the existing ones have froze causing the bearings to cut groves in the floor. Hoping I can put some stainless steel over the floor for the new bearings to run on. Any hints or help would be much appreciated. See attached photos.[IMG]onman44/SlideBearings?feat=directlink[/IMG]

The ones on the curb side are some sort of white plastic compound. They are adjustable. 7/16 socket with extension will get to them. You need to hug the floor to see them.
The road side bedroom slide has a permenant roller attached to the floor under both sides of the bed. These are metal.
