Has anyone used the Firm Feel 20:1 manual box

I don't know if this helps you or not, but here is my setup, and it absolutely sucks and will be changed when I am able.

• 68 fastback
• front tires 215/70/15
• factory disk brakes and suspension (no sway bar)
• original power steering box without the pump
• all sheetmetal up front and a 318 and 727
• tire pressure 30-32 psi

Armstrong power steering does work, but I can't negotiate a parking lot with a cup of coffee in my hands. Without it, it's easy enough.
