Pretty gutsy move. ;-) One thing to be careful about is that you
actually torque the CV joint bolts when everything's back together.
They've been known to come loose on you while driving if you don't
have the correct spline driver and a torque wrench. They will make
quite a mess of things when they come loose while driving.

Unless this was downhill or downwind both ways, or you were driving
40 mi/hr the whole way, your mileage was pretty astonishing for a FI
'71 and US gallons. I've never done nearly that well without a strong
tailwind.
You don't have smaller than stock tires on the front, do you? That
would skew the odometer reading. I can't think of anything else that
would give you mileage that good.
The repairs I do on gas gauges don't affect the gauge calibration at
all. The senders are strictly linear with depth of gas, but the tank
tapers toward the bottom and the "cup" inside the FI tank alters the
response even more. VW offset the gauge markings in an attempt to
make up for this, but they didn't do very well; we always get many
more miles out of the top 1/2 tank than we get out of the bottom 1/2.

Sounds like it's running great.
