I have just bought a rough 280SE 3.5 that has been sitting unused for several years. It has a rust free body but mechanically it is a bit of an unknown. I have got it running but the power steering has no fluid and the leak appears to be from the bottom of the steering box. Whats the procedure for removing the box, is overhauling it something I can attemt and how can you tell if it is worth overhauling.

I am new to this forum so hi to all!
