With the low torque of a 6 cylinder the lower first gear of the 200R4 would help it. I would go with 3.70's.

The 6 cyl doesn't turn a lot of RPM or make a lot of horsepower but it has low RPM torque so should pull the overdrive well.

It probably came with a 3.08, possibly a 3.31.

Install the OD transmission and change the rear gear only if you need to.
