Sloppy steering

[mntoy]

I recently purchased a 1974 C20 pickup truck, first thing I did was put a fresh 350 in it and the truck runs great. I have only owned this truck for about 3 months and for one month the truck was down to put in the new motor and it looks like the previous owner rebuilt the steering gear. The steering is sloppy, I have to move the steering wheel back and fourth about an 1/8 to 1/4 turn to go straight. The sloppy steering is kind of annoying and I have never had this kind of problem before does anyone know where to start looking to fix this or what the problem might be? Thanks,
