I replaced the cheap drawer slides that were used for the kitchen trash can in my Keystone Montana 5 Wheeler. Very easy to install. Simply remove the old slides, use a ruler to draw a line between the old holes and reattach along that line using the accessories provided. The holes will most likely not match your old ones, but that's ok and everything works great. The trick is to keep the guides on the same imaginary line as the old ones. The new ones are much stronger than the old ones and I am very happy with my purchase. I wish you success.
