I agree that the options are very limited, and the c151 offers a minor improvement. Can you comment on the feasibility of the c141 diff in the c151 trans? I have been researching this combination but I can't find a final word on these internets. My understanding right now is that the c141 diff offers a better ratio and will probably fit. Do you know?

Likewise. But on long highway climbs, anything to increase engine load and lower rpm would be great.
