Post some pictures of what the 2017 frame mounts look like. Maybe I can help, I installed my own pucks in my 2015 3500. SNOKING
Not to hijack, what was your reasoning for installing the factory pucks over using something like the GN to 5th wheel hitch that B&W sells? I'm looking at a 14 with a short bed that does not have the factory prep and am exploring my options before I buy. Living in the rust belt I'm thinking drilling one hole in a bed would be better than the 5 holes needed for the factory set up. Is there an advantage to buying/installing the Mopar puck kit over a turnover ball or is it just preference?
Thanks!
