Hi,
Dimwits aside... you can achieve part of the "effect" of the o/d by going 
to a 3.45 differential gear, which is what the home market cars have.
I'm pretty sure the US got the 3.70 diff because we also got less power 
from the carb'd engine. At this stage, there's not a lot of bone-stock 
cars out there, so the power issue is probably not present.
On the downside, you loose some accleration, if that matters.
I'm not sure if there are sources from NEW 3.45 gears, but there may be. 
Hokme market PI cars and TVR used the 3.45. I think some of the saloon 
cars did too (like the Triumph 2500).
Regards,
rml
