Quick Ratio Steering??

[nevada]

so my 72 C20 has power disc brakes and a/c but still has manual steering....I checked out brothers truck parts, even called them...they have a power steering conversion package. I asked if the new gear box is quick ratio , they said no.

Should i keep looking for quick ratio box? seems to make sense to me with power I dont need as many turns from steering stop to stop and I would think it would be more precise with less play?

am I on the right track or just buy their conversion kit? are all kits equal? which company offers best package?
