Considering the age of these cars, your gears could have been swapped out along the way and the tag lost. You could safely jack up both rear tires, and with it outa gear count the driveshaft revolutions for one complete rotation of the rear tire. With a t-lok, you'd find:
* just shy of 3 turns would be around 2.73:1 gears (depending on year)
* close to 3 turns would be 3.08:1
* 3-1/4 turns = 3.27:1 (or 3.31:1, depending on year)
* 3-1/2 turns = 3.55:1
* 3-3/4 turns = 3.73:1
* just shy of 4 turns = 3.90:1
* just over 4 turns = 4.10:1
* just over 4-1/4 turns = 4.30:1
For some reason, open rear-ends don't work with that method (they are half that). I need to read up on why that happens.
