I have the same problem. My drawer slide is marked Grant 336. I'm missing the nylon wheel on the drawer itself for the right side. I thought I could replace both drawer glides. However, there is nothing inside the cabinet for the glides to attach to. It's a free floating "L" like brace. Any ideas where I can find just the wheel of the 20" glide part that attaches to the drawer itself?
The 1st pic is the glide with the missing wheel
2nd pic is the glide with the wheel. and the 3rd pic is the inside glides.
Any suggestions or help would be greatly appreciated.
