Thanks 440 Offroader. I'll check Randy's site. Just by sight, I think this looks a bit different than the 8.25 in my Diplomat Police car, so I'm guessing 8 3/8". I have the Diplomat tucked away in my Dad's garage right now, so I don't have the cars side by side to look at though. And in the driving I've done, feels like it could be 3.21 gears.

Thanks again,

Larry.
