The power steering upgrade is turning out very well. The Saganaw steering box was a rebuilt model from an internet source and was very afordable.
I purchased the mounting hardware from Advance Adapters which made installation a snap.
The crossmember did need to be modified to allow for the steering box to be mounted and for the steering shaft that connects the steering column to the steering box. This was accomplished by taking some box/square stock and welding it in place of the existing crossmember stock.
See Pt. 2 for "the rest of the story" so to speak . . .
