So at the 1900 RPM at 70 MPH I was lugging the engine and a .8 would have been better for that use. I would say that 80% of my cruising was done in 4th gear as the traffic and speed limits stopped me from getting the engine up to where it ran well.

Perfect example of a need for a .82 and not a .64 gear. If you have a rear numerically lower than 3.5, or an engine that isn't at least awake below 2500rpm, I wouldn't go with the .64 trans. It can be a tricky call, and if in doubt, I'd go with the .82 gear.
