Ummmmmmmm, Jarod, this is an Oldsmobile site. But generally speaking I have heard the best way to do that would be to lift both rear wheels, use jackstands under the frame, then turn the DRIVESHAFT and have someone count the revolutions of one of the rear wheels to ONE turn of the driveshaft, and you have your ratio. And yes, 1.75:1 is wildly tall, never heard of that.
