Speedo gear ratio help! plssssssssssssssss?

the car that I'm working on had a 35 tooth driven and a 19 tooth drive speedometer gear assy. the rear ratio was 2.41-1from the factory- and the trans. was never touched- the parts book correlates that gear assy. too. The customer had put another rear end in the car and it was 2.73-1 and never changed the speedo- it read too fast. I determined with my limited math skills that a 38 tooth driven gear recalibrated the speedo.
IT read correctly.
Now the customer replaced the rear with a 3.73-1 and I am having problems finding out what the driven gear needs to be- any math wizards out there? please help me?
