power steering options!!!

[hpcgmc]

My next step in my project is to buy the power steering setup for my truck (67 GMC c15). I've looked into pulling parts off other cars/trucks and decided to buy new.

I've found at least four different options:
Ecklers for $700: http://www.ecklerstrucks.com/chevy-t...1967-1987.html
Tuckers for $625: http://www.tuckersparts.com/Power-St...t-F-PSK67.html
Brothers for $800: http://www.brotherstrucks.com/prodin...number=CPSK072
POL for $530: https://www.performanceonline.com/19...ONVERSION-KIT/
CPP for $699: CPP6772PSKS 1967-72, with CPP 500 Series box, kit $699.00

I think I also found a kit online for around $500, but can't seem to find that now. I'm planning on using a captain fab power steering adapter plate, since my frame isn't dimpled. http://67-72chevytrucks.com/vboard/s...d.php?t=332923

Here's my questions:
1. Anybody use one of these or a similar kit? If so, whats the good and bad?

2. What parts did you still have to buy, in addition to the kit?

3. Was it a pretty straightforward install?

Thanks!
