Drawer slide fit

The 21-061 is only 1/8" larger than your overall drawer depth, so my concern is that it doesn't have enough clearance out the back of the drawer to fit in a socket. Can you tell me what the length of the original track is?

Thanks! I can see why you're pursuing the 32-061 now. Our 32-062, being the next size up at 23-5/8", would likely be too long, since your total cabinet depth is only 23". I have heard of customers who cut the end of the track down with a hacksaw but that's obviously not ideal. 

We unfortunately don't have anything in between. Based on the specs given, I do think that our 32-061 would be too short for your drawer, though I also think the 32-062 would be too long. If either is going to work, it's going to take some adaptation.
