B&W Gooseneck

[Makkat]

Has anybody tried to fit the B&W gooseneck for an 11-15 on a 16-19 2500 HD?  In looking at the installation instructions and parts list the only difference I can see is the earlier model uses a through bolt and guide for the side plates to the frame versus having the threaded frame on the newer trucks.  I can't imagine B&W making a new model number over a bolt difference but I do not see any other differences.

 

I am trying to find a used hitch for my '16 but only seem to find 11-15.

I looked/measured my bosses '15 and it appears the threaded holes are in addition to the holes used with the earlier hitch, i see no reason an earlier hitch would not work.
