Mechanic, I have the old bell crank system on the truck now with the old dana 27 closed steering knuckles. The newer dana 44 has open steering knuckles with the pitman arm setup. The power steering gear mounts on the inside of the 64 frame. The saginaw box that I got with the later wagoneer front end mounts on the outside of the frame, farther forward. I knew about the adapter for the 350. He,my son,now says he wants it to be a 2 wheel drive pickup. We would swap the 350 chevy engine,350 trans and the 10bolt 3.73 posi into a 50 ad frame. As I said 20 year olds have some wild ideas. I haven't been on for awhile because of coaching high school football. I think this will be my last season, may retire from teaching next year also.
