I am winding down for the start of winter, just a few small items to tie down. One of them is the Steering wheel, how do I keep from getting black hands when I use the steering wheel? Also I need to tighten up the slop in the steering if possible. It is on a 1941 Farmall A. The steering wheel black is all there it just leaves a black stain on your hands. The slop is about a third of a turn. Is there a adjustment somewhere to tighten it up?
