"How long you do think it would be before he could recoup the cost, through gas savings, with the 700R4, torque converter, and condiments".
The answer is never! If I was looking for return on investment I would have been broke a long time ago working on these old C10 trucks.

Replacement parts for the three on the tree are just not out there. Maybe a worn part can be repaired? Or do what has been done for years, convert it to a floor shifter?

Least inexpensive fix is likely the conversion to the T-5 from an S-10 as mentioned. If you did the work yourself it could be done for the price of the manual floor shifter for the 3 speed.

However, you wanted an automatic. The old 350thm are still out there and would be stock for the 1969 and up C10's. The are also the same length as the Power-glides. Should go right in and again will not require any driveline work. I would add a used column with the automatic shifter and never look back. Don't forget the transmission cooler. A replacement radiator or just and aftermarket add on will suffice. But I am spending others money which I am very good at. LOL
Cheers.
