Cabinet rollers

Hi,
I'm hoping you can take a moment to help me out. I'm desperate to find the roller parts for a 40 year old, Geneva Kitchens (now out of business) cabinet. The cabinet has two sliding glass door with metal frames that both slide left or right on a track at the top of the doors. The rollers are the standard plastic material that after 40 years has fallen apart. The actual roller pieces are 1/4" offset with an 11/16" roller. The only information I can get from the part itself is that the wheel itself is stamped with the following:

2550 Sterling

It seems this part hasn't been made for many years and I was hoping that you might have access to some and/or know where I might turn to find the part. I only need one piece but would take more as backups if you had them. I'd really appreciate any kind of response from you, please. Thanks, Glenn

Hi Bob,

Thanks for the reply! They aren't for drawers. They are for a large cabinet that we use as a surgery supply storage cabinet. The unit stands about 7 feet tall by 3 1/2 feet wide or so, and has two vertical sliding doors that are made of glass with metal frames all around. These door both slide either left or right on a track which sits below the doors and the rollers pictured are at the tops of the doors running along a second set of tracks. 

 item 23-009 might work but the dimensions are too tall and too wide. Something exactly like this item but 30-40% smaller would be ideal. Do you have anything like that? 

Again, thanks so much for helping when no other company or place would!!! Glenn
