Hey Bo. I have attached a dimensional diagram below of the 1/4" Filler Shims for Gen-Y Hitch Executive Fifth Wheel Pin Boxes item # GY76FR. These 1/4" thick shims adapt a 12" wide Gen-Y pin box to a trailer that has a 12-1/2" wing width. These will work with any bolt pattern a Gen-Y pin box will fit.
What kind of 5th wheel trailer do you have and what pin box are you looking at upgrading to?
