Does your truck have the original wiper arm linkage/knurled attachment lugs?

If so the corresponding Trico wiper arms slide on to these and lock with a small clip (on the wiper arm). It is my experience that this OEM arrangement is a pretty secure system, first time removal is what I base this on.
Do the replacement arms tighten in this manner or with some sort of set screw? If they are set screw type before you damage the arms I would see what others may reply with, my experience with them is they may be more problematic over time. Set screw types will destroy the original fine knurled area, if this happens original arms will no longer work.
