I have been looking for a power steering setup to put on my cruiser while its getting restored and I found a box from an old chev nova subframe sitting in my buddys yard and it has 4 mounting bolt holes on the box(only 3 bolts were used to hold it on the nova sub frame) anyway it only turns three turns lock to lock?? anyone know if this is the right box to be using for a power steering conversion on a 72 fj40 with a 2f?
