Steering Wheel Adapter Help ! Lots Of Pics

Hello,
I am trying to upgrade my steering wheel from the basic one to the better-looking one.
I removed the basic one from my 2003 FL112 Truck,
I got a steering wheel from a 2010ish Cascadia, When removing those three bolts from hell on mine I managed to remove the steering wheel and the Hub from the spline/shaft.
My issue now is that the splines on the shaft from my 2003 is larger than the splines on the steering wheel from the Cascadia.
Does anybody know of an adapter that will fit?
Here are the pictures showing the splines difference.

This is the steering wheel I want to install, the splines are smaller, even the shaft is smaller:



Here is another shot:






Now here is the Hub showing the size of the splines currently in my truck. So I need an adapter from large to small:

 

Alright! I got it. The steering wheel is aluminum, however, the spline part is steel pressed in. Since I don't have a press, to press it out, I cut it off, drilled, and bolted the original spline.
IN the truck the original spline was also bolted to the OEM steering wheel. See it below.
