Axle ratios

[Britcannuck]

How can I determine what the rear axle ratio is on my 03 Ex.
The plate on the door pillar says H6 but the only thing I could x ref that to was an '85 Bronco.

My same model tach's 1950rpm @70mph= 373 ratio

I don't think there was a choice on the 03 was there? I thought 3.73 was the only option.....
