Which steering box?

I have 2 firm feel manual boxes. A 20-1 in my 72 and a 16-1 sitting for when I pull the motor again. I like the 20-1 box feel in the car vs the 24-1 that’s stock. Don’t know how the 16-1 is in my car yet. Some of this choice was I also did a full suspension kit and was cheaper to have them do the box. Also I live about 10 minutes from them, before they were total sticklers about only shipping. My buddies, @lead69 and loud-mouth I believe have PST boxes in there darts and like them. So so looking at price of FF build with the quick ratio ($550) think it is now vs. PST ($250) is something to consider..
