I have an issue, I'm building my car, 83 malibu wagon, the it started as a frame off, so the frame was stripped and I am lacking a steering box. I have purchased one from a 94 jeep grand cherokee but have no clue what pitman arm I need. So far I have seen arms for a 800 box and a metric box. They seem to be different lengths. Can anyone shine some light of wich one would fit the 88 steering components with the jeep box?
