Borgeson 800126 (Small Sector) Quick Ratio Steering Box Applications

1972-1970 Dodge Challenger

1972-1970 Plymouth Duster
I am about to replace all the power steering components in my 72 Duster with Borgeson. I just want to make sure I am getting the correct stuff.
The pump is PN 800337
Steering box PN 800126
Coupler PN 036425
Hose kit PN 925113
Does this look correct? Any tips/tricks? I've never done anything like this so I'm rather nervous since being able to steer is kind of important.
Thanks!!!!
