I'm trying to get my frame stripped so I can take it in. I'm removing the front axle and springs now and am trying to pull the pitman arm. I went to napa to get a puller and all they had was one that was pretty wide. I didn't think it would fit in the indented area (not sure how else to describe it). The truck is a '53 chevy 3/4 ton. The napa part number if someone wants to look it up was Part Number: SER 2289. Do they make these in different sizes, is there a specific one I need? I tried to use my little bearing/pulley puller (its not very big) but it kept slipping off when I got quite a bit of pressure on it. Any ideas?
