How to modify 5axiskins from BC head to AC head

Hi,
I was hoping somebody might be able to help me with modifying the 5axiskins kinematics to rotate the B axis 90deg and rename it to A axis.  I have everything moving and working with the 5axiskins and switchkins, but to match up with my machine setup I have to rotate and offset the B axis 90deg. 

Thanks. I'll have a look at it.

I don't have the sim/axis/vismach/5axis/table-rotary_spindle-rotary-nutating/xyzbca-trsrn_twp/ listed in my sample configurations. I was able to find the thread where you're discussing it and I downloaded the files, but I'm not able to get it to run. I found the readme filed and tried to follow the instructions, but I went wrong somewhere.

Added photo: This is how my machine is setup.  It's a bit silly because I have two "C" axis setup.  Specifically I want to use it to make drums so I wanted the rotary table to keep round things more concentric than just interpolating a circle.
