I need measurements from your c/k series duallys

I am trying to narrow down some info on the widetrack, gt4 option some of our trucks have. What I need is the dimension of the dually fenders, from the bed side to the vertical part of the outside.
Then I also need the width of the axle from wheel mounting surface to the same on the other side.

Also let me know if you have the gt4 option or not.


Thanks

How do you tell if you have the gt4 option?
