Did a search already and couldn't find much info. I can't remember what the P/N was for our power steering boxes (in need of one). The guy at the parts place asked if it was 32 or 33 spline. I cant remember that either (threw away the old pitman arm years ago). Any one have this info for a fellow Dmaxer in need? It's on my 02 3500 if it matters (cant remember if it does or not). Getting older is definitely not for the faint of heart.
