PowerSteering?
Clearance is super tight with TTI headers and manual steering. I am using a flaming river box and 73+ style steering linkage. I tried moving the engine and trans slightly in many directions, and it doesn't seem to help much. A gain in one place is a loss in another. Hopefully I won't find the extra steering effort to be more than my wife is willing to put up with.
In addition to the adapter for power to manual you may need a different pitman arm since there are two different shaft sizes.
