Is there an adjustment on a 73 Mav's manual steering gear box to tighten it up a bit? The alignments great. Toe in /out etc. The tires new. Balance good. I just don't like how easy it is to steer it. Especially on the highway. My daughter drives this car and I am a bit paranoid that she may lose it on the highway if she gets distracted. I would like to stiffen it up a bit if it's possible. Thanks Lennon
