67 Valiant power steering way too touchy

I got my girlfriend a 67 Valiant a while back and were just getting it on the road. I'm driving it around and the alignment feels ok but the power steering is crazy touchy. It's almost hard to drive in a straight line because you have to keep the wheel so still. Kinda feels like bumper car steering where I could make a hard left and the car would just rotate in the center and pull a 180* on a dime lol. Is this normal or is there some kind of adjustment I can make? This is my first time driving such an old car with power steering so I'm not sure what feels right and what doesnt.
