Lares 11043 fast ratio questions

[1KoolBee]

So all of the recent discussion about steering boxes for me thinking about my 67 GTX clone build. I’m at a point where the k-frame/suspension/engine/trans swap can happen and I’ve got a few questions about the Lares 11043 box.

1. Does ‘70 Saginaw style pump have sufficient pressure/volume?
2. Is pitman arm shaft small or large style?
3. Does it bolt up with factory steering shaft coupler?
4. Does it provide any additional header clearance?

Experiences appreciated.

I put in an info request to them from their website asking about fitment. Direct bolt in or mods required. Don't see much on web searches. I'll share info when I get it.

The Saginaw power steering pumps were purported to put out over 1000 psi in V8 applications and around 750-800 in the slant six models. Rick Ehrenberg made such claims in the "Pump it down" article he wrote in Mopar Action magazine.
It all came down to the thickness of the shims that are installed in the spool valve of the pump. More shims equals lower pressure. This is partly why replacement and rebuilt pumps often have no shims....they aim toward the high end of pressure.
