If you are going to allow the 6-Volt IVR to handle the 12-Volts, you obviously don't need to do ANYTHING with the IVR. If you are considering adding a solid-state regulator ahead of the IVR, as I have done, and as the Ford guys I linked to have done, you don't need to access the IVR... just find the wire that powers the instruments.
I was thinking the old Ford may have a small fuse block? Some years ago, I did this with a 1953 GMC, and IIRC, the gauges were fed by one of the wires on one of the ignition switch terminals. I sure don't know for sure where your old Ford's instruments get their power, though!
As far as accessing the instrument panel, even if you don't have to get to the IVR, you'll have to change the dash light bulbs to 12-Volts, so you're going to have to get at the back of the panel, no matter what.
Sorry to hear about the vertigo problem. Fortunately, I don't have anything like that, but my bones and joints don't handle being wedged up under the dash as well as they did 20 years ago!
If I get time, I'll snap a photo and post it later of the voltage regulator I installed on my old GMC about 15 years ago.
