with a manual steering box that is new or rebuilt with new parts in every place but the case, on a re bushed and overhauled front end. there is no slop.....the only flex you feel is bushes compressing and the slightly bendy feel those thin track rods give when near left or right hand lock. if you add in ford truck sway bar links a better idler bush and the box is 20:1 or 16:1. Set up with the car ride standard and level and a modern alignment you are onto a GOOD thing even with $26 KYB gas adjust at each corner. It works in a manner that is not only acceptible but quite impressive... These days you can buy a box for cheaper than rebuilding one in just about any case where a sector shaft or ballnut and screw needs to be replaced. 2 retail cartridges of grease is gonna be $80-100 unless you can "borrow" some from a bulk pack at work.
