[TR] 4:10 diff

[Brad Kahler]

Listers,

Now that I have the TR4 street worthy and have been driving it I've come to
realize that the differential in the car is a 4:10.  I've verified this by
comparing tach readings with road speeds via GPS.

So that leaves me with the problem of the speedometer being way off.  This
is the speedometer that was in the car when I got it so either the
speedometer was replaced at some point or else the diff was swapped out for
the original 3:70 diff.

I'm looking to find out which speedometer would be correct for the car,
i.e. what numbers would I find on the front of the speedometer that would
indicated it is for a 4:10 diff?

Thanks,

Brad
