I think you will find the pin extension does the same thing as the slider.
Not at a 90 degree angle. At 90 degrees, the 5th wheel is moved farther outward from the longitudinal centerline of the truck by the extended pin box, but not farther rearward from the cab. That distance is determined, as I stated, by the distance from the hitch kingpin bore centerline to the rear of the cab. If you have a 102" wide 5th wheel, then if the distance from the hitch kingpin bore centerline to the rear of the cab is less than 51", the side of the 5th wheel will contact the cab when the two are at a 90 degree angle.
It's basic geometry.
