1956 Speedometer fitting ratio?

[odlewis]

Hi
Can someone tell me if the 90 degree speedo fitting at the transmission a 1:1 ratio? Also does it turn in reverse or direct?
Thanks M.L.

Not sure of the ratio. Im fairly sure it rotates the cable in reverse. But I'll check this afternoon if no one chimes in with an absolute response.

The cable is turned in reverse, and from what I marked on my angle drive, the speedometer gear (now made of plastic) does turn my cable very close to 1:1. I have seen different speedometer gears sold at the Thunderbird houses offer different teeth count. Mine has 19 teeth.
