Steering Box Ratio
I'd recommend this route.
--The rebuild kit I have is the PST polygraphite kit and if I go with the included pitman and idler arms, I can use the stock '65 V8 centerlink that I already have. If I go this route, I can go with the 16:1 steering ratio.
In either case, though, I'm probably going with the 20:1 steering box ratio just for driveability.
