My part is just like your part # 32-140 with one difference. the inside end measurement is 1 1/16" not 15/16". do you have anything like it?

I'm afraid I haven't been able to find a drawer socket with these measurements. If you can, please send us a photo of your track, as well as one of the bracket you now have. Perhaps we could find a work around.
