When I removed the gas gauge I looked inside the tank, and it looks like new, beautiful grey with no evidence of rust, almost too new.
Is there any way to inspect the bottom exterior of the fuel tank above the steering column without huge dis-assembly? Is the steering column riveted directly tot he tank?
How is this repair done without dis assembly?

To answer your question directly, it isn't. You will have to remove your gas tank, have it boiled or steamed out by a knowledgeable radiator shop, silver-solder the bracket/leaking area, pressure test the tank and reinstall the gas tank. Do not allow anyone to weld the tank, the hardened sheet metal of the tank will spider-crack if you do.
Part of the joy of owning these sometimes frustrating old vehicles is doing the maintenance and upkeep on them. Part of the joy of doing the maintenance and upkeep on them is doing the job, however difficult, that you know needs to be done in order to keep them running properly and safely. Happy Motoring!
