SFWIW, trying to find the right glide can be a real PITA.

My solution, make your own.

Go to a plastics distributor and pick up a piece of filled PVC sheet,
say 3/8" or 1/2" thick.

Cut PVC pieces to the req'd sizes, counter bore a couple of holes (I
use #8 x 3/4", pan head S/S sheet metal screws /w/ a washer) for
mounting screws, and get a beer.

You owe yourself oneG.
