While we're on this thread what are people's thoughts about covering the holes in chassis legs? On my "flakey" 120 there are a few 1-2" square holes from the factory, and unsurprisingly a good depth of mud inside the rails. If starting from a new, clean rail would it be better to seal them up, or are they needed for any moisture to have a chance of evaporating. I have to drive through a shallow ford every day so there is always water getting close.
