alignment question.

[nateshrek]

Hello gentlemen,
I have a question on alignment of my 65 gmc. It has a pull to the right, which makes it handy when going around right hand bends other than that, it's a consistent left hand, elbow out the window cruising position. My question is what's the process of getting that straightened out. It's slightly lowered but the kicker is it has 285/50/20's on it. Your knowledge would be greatly appreciated by me and my left arm.

Thank you for your time guys.
