Newbie needs help on buying truck

[jim-roberts63084]

okay i called the guy and there some issues i wanted to address with you folks.
1. it has disk brakes in the front and drum in the rear no power, how hard would this be to be to convert to to power? simple as bolting brake booster in and running vacume hose?
2. He says the the truck turns sharper right then it does left by just a hair and said its because the pitman arm or idler arm wasnt changed with the lift, and said when you turn left it doesnt clear the knuckle? Said he has the right one (exteneded) one that he will give me with the tuck if this makes any sense?
