i have a 92 w250 4x4 5. 9 and i need a new pittman arm. i have tried every local parts store in town and none of them list that part. every time i go to dealership they can not locate any thing that old or just dont want to. im not sure. any way im down and cant move till i locate a, oem pittman arm. any help would be great on a line or where to go and get one.
