Does Reese M5 5th Wheel Hitch # RP30928 Fit Rails 22 inches Apart Marked CMI


My 2015 Chevy SIlverado 3500 has a rail kit from the previous owner. Im not sure which rail kit this is CMI is stamped on the top center???, so I was hoping you could verify a couple measurements for me. The outside slots are 29inch apart on center from left to right and from front to back are 22inch on center. The slot openings are 9/16 by 1 5/8 and the holes for the locking pins are 1/2. Will these line up with the tabs/holes on this model of the M5? Also, does this hitch come with the locking pins? Thank you for your assistance.
