Jerky, poppy steering (74 Duster, 318, 904, auto, column shift, power steering car)

Hey, everybody. I installed a replacement steering column in my 74 duster, and before, it was pretty jerky like it would hit "pockets" of steering and then be sort of loose and have some play in it between the pockets. It's a power steering car. Now, it's a little worse than what it was. I have a Grant steering wheel and mount on there as it had before. I was just wondering if there are some things that I could check to make sure it's doing what it can etc. I'm not expecting a modern car feel, but I would like it to not feel like complete **** either!
