‘63 Valiant - steering shaft play

You don't have to disassemble the steering column, but you should remove it from the car. Just remove the two bolt holding the column to the dash, and the 4 (3?) bolts holding the firewall bracket that supports the lower end of the column. Disconnect the turn signal harness, then remove the bolt and nut holding the coupling to the steering box (later models use a roll pin), and pull the column out. Much easier to mess with the coupling when the whole column is out of the car. Actually, I've never done it any other way.
That seems easy enough. This is an attractive proposition to me, for a couple of reasons - I want to patch cracks in the steering wheel, and replace the broken piece that returns the turn signal arm (I have the part, just forget what it's called). And I can take it to a machine shop in the event I need to press out the shaft to shoe pin, instead of to the car shop. Also, I can assess the condition of the housing. There's a key spline for the housing, correct? Only one way to put it on?

I spoke with Rick@Laysons, and ordered the kit. Thanks for the advice!
