Alxe Ratio for 66 inline 6 ?

[66moneypit]

Anybody know which axle ratio the 66 inline 6 came with ? I did a search couldn't come up with it.

read the tag on the diff.

jack up one of the rear tires, spin it one time around and count how many times the driveshaft spins.

All that's gone dude.... I bought the car as a 6 and converted it to an 8 but I'd still like to have a door tag with all the original information. I have all the other data but I don't have the ratio. I sold the rear end already...

The original rear end that came with the car is gone.... I have a Granada rear end in the car now. I wanted to know the ORIGINAL ratio for the 6 cyl Mustangs. Not what ratio I have now. That's the only piece of info I need for the data plate.

well there is no real way to tell. the ratios that it came with were 2.83, 3.20, and 3.50.

My 6 w/c4 has the 2.83

More than likely you will be 2.83, but to be sure check with marti auto.

Thanks for the help guys.... I figured as much but wanted validation from the gurus.

I didn't think Marti reports where available for 66s.

the mustang restoration guide i have doesnt show 2.79's comming in the 7-1/4"

depends on what 289. is this a regular mustang or a GT? even then, there are a lot of gears to chose from.
