42 or 43" Center ski stance

[Motorhead]

I noticed that my sled is set up with a 42" ski center to center distance.
Did I read somewhere on this site where this is adjustable to 43"?

Looking at the ski spacers, if I were to move the 1/2" spacers to the outside of ski I would also have to turn the rubber bumpers to match?

Seems like wider should be better for stability, but would it push more in corners at 43"?

Found the older thread. Move spacers and turn rubber bumpers. Shall try it both ways.
