Steering box recommendation....?

[NovaSF]

With the motor out of my 1970 Nova I'd like to replace/upgrade my steering. The car is street driven, no autocross (maybe someday). I'm going absolutely nuts trying to find a reasonable replacement that gives 14:1 or 12.7:1. Everywhere you look is the CPP 500 box but I've heard and keep seeing bad stuff about them. The 85 Monte Carlo SS box is like a unicorn as well. Below are the 2 options I'm leaning towards.

Any thoughts/suggestions?
