i have a question...i got my power steering box from lars for my 1956 oldsmobile ..how does one take off that metal piece off the old box and put it on the new one so the rag joint can bolt up...is there a metal pin i need to punch out where that side hole is? and is there a tool to pull it from the splined shaft? i tryed to see if the pitman arm puller would fit but wouldnt go around...thanks
