drawer rollers

Purchased a condo that has drawers, circa 1985, several of the rollers are missing. Eventually they will be replaced but not now. Cannot find them here in Las Vegas. They attach to the back where the sides are longer than the back. they are left and right and have an L shaped mount. The larger part is 1 in.W & 2 in.L with a slant toward the wheel & has 3 oval holes & 2 screw holes. Narrow portion is 3/4 in.W & 2 3/4 in.L including the wheel which is 3/4 in. plastic with ball bearings. They resemble your 32-040/041 except the wheel section is much to long. Sure hope you can help.
