Depends on what you are wanting. One is going to give you a lower cruising RPM. If It were me I would go with the the .64 to give me better MPG on freeway. Who uses overdrive for pulling power anyway. Is the final drive only gear different?

I'm not sure I'd the other gears are different. I was wanting the one that got better gas mileage but I wasn't for sure witch one that was I know nothing about the ratios in transmissions. They run about 2500 brand new with bell housing yoke and fluid. Its a 5 speed

the .64 will give you better gas milage, the other one will give you closer ratio if you were road racing or going for top speed.

.64 is the one to go with. Its overdrive, not another gear you use to race. The other od ratio is for road racers that actually use 5th for another gear when they are on an open road course with long straightaways.
