Hi again,
Russ's comments below seem to hold a ray of light.... My speedometer has
"1280" on the face of it near the bottom on the right hand side.... Now....
If I knew what the speedometer of a car with an overdrive unit had on it,
I would be able to work out a ratio..... and well, the rest would be easy....

David -
Can't help you with the second problem, but the first is easy. Just give
the speedo to an experienced shop and tell them to set it up for the new
ratio. When I put an early '70 tranny with OD into my '63 non-OD car I
thought a lot about various different angle-drive adaptors but just gave
up. Then, for not much $, it was a done deal at the speedo shop.
The inconspicuous 4-digit number printed on the face of the speedo is the
number of revolutions of the cable per mile. Find out what the number is
on the speedometer in a car having the OD tranny you're installing and tell
the shop to set it up for that. DON'T let them put the car on the
treadmill and run for it for a mile to get a conversion factor like I did
initially - it's just not very accurate.
