can you compare the vertical and horizontle splined shafts splined clocking position(s) on the old box to what you have now?
RR, I returned the old box some time ago or I would double check how things line up. I did a comparison when I got the new unit but don't have any pics to go back and look at.
The only thing I can think of doing is turn the wheel past center and see how much travel I lose on one side. Unless there is something else I am not seeing.
I might be thinking what you're thinking, The new box may be off internally making the input and output shafts out of line.
