I hate posting this since it has nothing to do with a y-block but this is the only website that I get great and fast answers.

I am trying to remove the steering column from my 56 Crown Vic.  The wheel is off, the column outer tube is out.

I am left with a steering shaft that goes directly to the power steering box and I see no way to detach it.  It feels very solid to the box.  Searching one website someone said the shaft is permanently attached to the box.  Yet, when I find a power steering box replacement it shows a spline to attach the shaft??

So anyone have an answer for me?

Thanks Guys
