Have CPP power steering kit, input is *real* sloppy. Ideas?

[yossarian19]

I've got a 57 longbed with the CPP power steering kit, which puts a '70s box ahead of the front left tire outside the frame rail.
The supplied intermediate shaft is kind of a joke. I mean, it's present and it is made of steel - but between the two joint connections and the loose slip-fit of the collapsible steering shaft, the wheel moves about an inch and a half or two inches before steering happens.
Other than that, I've got all new rod ends. I've got a 7/8" solid tie rod between the knuckles. The bearings are tight & greased. The kingpins are new and pretty tight.
The box I bought could be better, I got a Lares and am not over impressed...
What else am I missing that could contribute to this slop in the steering?
If I'm down to the intermediate shaft... what are my other options? Anything from a junkyard likely to work for me?
