Searching for Side mount drawer slide 19.75 in long

Hello. I need to fix the drawer in my bathroom vanity. The rear drawer track socket broke. I took the slide off the drawer and the glide that it fits in to slide into place. Your 32-012 looks like it will be a great replacement for the rear socket. I lost the glides--ugh! So, I need them, too. The one attached to the drawer is 19.50 inches long. The piece mounted inside the vanity is 19.75inches long. This is only one side, but send me for both sides so the drawer matches on left and right. I really hope you can help.
