Re: What rear gear do I have?

I see your tire size is closer to 28.9"
In the transmission calculator I got:
Ring & Pinion: 3.5
Tire Height: 28.9
Engine RPM: 2000
Transmission Gear Ratio: 0.696
Vehicle Speed: 70.62
If I change that to 3.73, I get 66.26, so you would be over 2K RPM at 70 mph. Played with it a bit, ~2100 RPM at 70 mph.
