There are conversion joints for most types of u-joints available.
Meaning that you can use the smaller/larger wider/narrower driveshaft
yoke with a dissimilar rear end yoke. I use two different mopar 8.75"
pumpkins in my AMX, one with 3.90 gears for fun around town and one with
2.8? (not positive what the ratio is) when I want to go on a road trip.
They are not the same series case and use two different u joint sizes,
to make them both work I just swap in the conversion joint when mounting
the smaller of the two. Same driveshaft two different sized rear end
yokes.

Make that 106" wheelbase 64-69 Americans. Won't work with an AMC20
because the U-joint has larger diameter caps (joint is bigger). I'm
reasonably sure the Pinto wagon has a longer wheelbase than the
hatchback. Not 100%, but...

If you have a 72 up AMC 232-242-258 six with a T-5 transmission and an
AMC15
rear axle in an American sedan, yes, a 77 Pinto wagon driveshaft is a
bolt in!
  I'm using a true 82 Spirit T-5, it's overall length is the same as a
Ford T-5. So barring unforeseen differences car-car this "should" be a
bolt in to all American bodies that share the two door sedan wheel base.
I'm not sure what the AMC-20 rear axle would do. If it's pinion is
longer or farther forward I do not think it will work as it is a "tight"
fit in my combination. Take a tape measure to be sure, though it would
still be a good starter shaft to have cut if needed.
  The best part is the Pinto shares u-joint sizes with the American and
is larger in diameter to boot! I found this by taking a tape measure
into a Yard and measuring shaft lengths till I cam across this on. It
was from a 77 Pinto wagon with a 4 cyl auto to be exact. IIRC even the
yoke will fit in the Ford version of the T-5! It does not fit in the AMC
T-5 as it uses the Chrysler 904 spline. :[
  Mine cost me $25! :] Sure beat having one cut or built!
