Guides and springs

Manuela, thanks for the quick response. I sent 3photos two are the top and bottom of the door. Using a caliper the diameter of the guide is 0.3700 inches and the rails are 0.3870 on the average. Since I have new rugs installed I think replacing the guide caps and springs are my best option. The other photo of the label says they were installed in1990 which is when the house was built. So I need the part numbers for the guide caps and springs. Thanks in advance Tom Rezba. Could not any other marks or numbers.
