Compatibility of Threaded Anti-Rattle Screw with Curt Channel Style Ball Mount C45900

Question:

Your info says that the subject set screw will work for the hitch ball mount 45900. The info presented says that it will need to be intalled from the rear of the hitch. There is no place to do that on the 45900. Also I came across some info that it was only compatible with the 45902 and 45908. The 45900 I just purchased has the rubber anti rattle set up. Is the set screw supposed to be installed there.

The Replacement Anti-Rattle Set Screw with Wrench for Curt Channel Style Adjustable Ball Mount # C45916 is a set screw that is 1/2" -13 x 1" bolt. I reached out to my tech contact at Curt and it is not designed to replace the rubber anti-rattle plug included with the Curt Adjustable Ball Mount # C45900. The rubber plug was actually created because of issues with customers overtightening the set screw and ruining the threads on the anti-rattle so the rubber plug anti-rattle was the solution to the set screw issue.
