You can put the car up on stands and count the number of turns of the driveshaft in relation to one rotation of the wheel. Less than 3 rotations would be a 2.73 and just over that would be a 3.08 and so on and so forth.

I couldn't tell you. There should also be a tag on the rearend that will indicate what gearset if they have never been changed. I'd count the rotations if you're questioning what gears might be in the rearend.

If you're going to have the cover off, take a look at the ring gear. It will be stamped on it if they are Ford gears.

Actually its the other way around. Some of the autos also have 3.27s.

Then you have 2.73's. To fit 275's in the back you would have to roll the fenderwells and remove your quadshocks.
