I also got the seat brackets and paddle shifter in, the brackets line up in the front holes but not the back, so I guess I'll need to drill the floor for the back holes. The steep angle of the brackets makes for a ton of leg room, almost too much. They go way back to the point where I will barely be able to touch the pedals, and I've never had enough leg room in anything. When forward it raises the front edge of the seat up maintaining a lot of leg room even forward and my Recaros have adjustable thigh supports on top of that. I guess no one short will ever drive this truck.
...and here is the paddle shifter, really nice piece:
My steering wheel is still lost in Italy somewhere, but as soon as that comes in I can measure for the column length.
It's all a puzzle, the seats and brackets change how far you are from the dash, the paddle shifter changes the overall length of the column, and the steering wheel has a different dish from stock, so in order to know what the length of the column needs to be you need all the other pieces.
