What options for O/D behind a S/6?

At this point, a non S/6 swap is NOT an option. FWIW, I average 20-22 mpg in my 4400 lb '93 Dakota with 3.9l / AX15 5spd / 3.21 8-1/4" and cruise control. And it weighs a WHOLE lot more than the Valiant. Currently only looking at S/6 O/D options, I have a strong 40k miles 225, with A/C components already installed. Also a40ish k miles 3.9l saved from a destroyed van body due to how well it ran, again with a/c components installed. Either engine coupled with a '62 dealer installed underdash A/C unit fixes any FL specific short coming we may have to overcome with this car.

Personally I believe this entire discussion resembles using a space shuttle to go roller skating. There is no easy or cheap AUTO OD unit than will be cheap enough to ever recoup the install cost vs the small increase in mileage it "might" give you at least in the case of a slant in a light body

If you don't want to put an OD A833 in it, I'd leave the thing alone. Put your money into Decent Tires and a Really Good Tuneup. Examine the rear axle ratio, but I'd bet you won't improve on that
