Hot Rods Power Steering in a 1957 Chevy NAPCO Pickup with 348

I have a 1957 Chevy NAPCO pickup with a 348 Chevy installed. My question: Has anyone with the same setup as myself, tried the CPP power steering install (CPP5559PSK-OC). The problem is the clearance between the header and steering box. Also, if so, what steering column did you use?
Thanks, don

 

Here's a bump for ya...... I like them old Napco pickups.....

 

btt

 

What about the kit that moves the square body steering box to the outside of the frame ?
