'14 Overhead console O/S Dimensions

Looking for the outside measurements on the overhead console that would be in these trucks. Thinking of taking some Black Walnut that I have and make a console. From service manual there appears to be anchor points to use. Main use would be a 2 way radio and maybe a cubby. Just thinking about freeing up some space along with creating some. Had a radio overhead in another truck and liked the access and ability to see and hear. Figured I make what I need and have seen some nice ones online! Wish they still made the Shelf-It to fit this Gen of trucks! TIA.
