John, I had always heard the rumor about overdrive cars coming with a 4.10
rear gear also. However, I can tell you from experience that I don't think
it is true. I have parted out at least 20 TR-3, TR-4 and TR-4A cars, many
of which were shipped from the factory with an overdrive, and I have never
found one with anything but a 3.7 rear gear.
My guess is that the 4.10 was on option which was available, but wasn't
actually shipped on very many cars.
