Ben,Well, the four speed sure is easier to find...but I was assuming that the 5 speed was an overdrive 5th... thus taking some of the fuel mileage penalty off the change to the 3.46 axle...but retaining the low end... Is the 5th gear not an overdrive ratio ?

What?, you have done 4 or 5 or more change overs to manual trans.... I think it is a little late to avoid typecasting...
