Good to see you back. As long as you could spin the shaft, by hand, your good. If you lean on each tire ( with the car off the ground) and push to turn it, it should move rather easily. If it does, your probably good there. While the car is jacked up, use a piece of chalk and mark the tire, I like to make an arrow that points straight down to the ground.
With that arrow pointed down, make a mark on the driveshaft and right in line with that mark, mark the pumpkin (housing / other side of the u-joint)
Now turn the driveshaft slowly by hand or strap wrench / whatever , but count the turns the shaft makes and don't make but 1 revolution of the tire!
Obviously - if the driveshaft turns 4 times then you've got a 4:1 ratio, if the shaft turns 3 1/2 times but the tire turned once, then you've got 3.50 :1 ratio, etc etc.

This will get you close enough for now. ( as far as knowing the ratio )
