hard front end shake and pulls right 1980 c20

[dragn91]

Well I have been working on my new truck the last couple days and this just got worse. It shakes violently at around 45 and doesn't stop all the way to stopping. Sometimes it's fine but shakes more than doesnt. It's done it since I got it but now is worse. I did switch the front tires around and also installed a new passenger side caliper brake master cylinder and all new rear brake lines and hose. I'm hoping it's just a wheel out of balance I'm going to have the front wheels done tomorrow and as soon as I find a semi decent pair of rear tires I'll get those done. I don't want to pay for an alignment because I'm going to be lowering it in the next couple of weeks my question is if the wheel balance doesn't fix it what should I be looking at and how can I check it as far as steering and suspension. I know suspension pretty well but steering components I'm not familiar on what is suposed to move and have play and what not.
