Dear Swisco:
What Bottom Roller assembly and track do I need? The opening is 58 1/2 inches and the rollers are convex, but worn. The roller assembly is 3 1/8 inches wide by 4 1/2 inches. The screw holes are 3 1/8" on the side of the assembly/ side of door and 2 1/4" ond the width or bottom of the assembly or door. I have enclosed pictures of both parts.
Thanks,
Paul
