Hey guys - I have a 2015 RGS - added the tourpak - which, I'm assuming is from an Ultra. It says it's "quick-release" which, in my opinion is not true. I finally got it unhooked, and off, but now when I try to put it back on, the little C clamps on the rear will not engage, they act like they're stuck - has anybody come up with a trick to get these reconnected, or is it simply a matter of overcoming it with brut force? Thanks!
