A while back, I had posted (Post# 53438) that I was having problems with 3 plastic speedometer gears being "chewed up" and failing. After pulling the tail housing and inspecting the drive gear (metal) on the output shaft of the fordomatic, my mechanic found the gear to be extremely rusted and probably the cause of the failures.

There is a NOS speedometer drive gear for the 1956 Ford Fairlane and Thunderbird on ebay (Item# 200619752981). The part number is 8M-17285 and it is correct for 55-56 Ford Fairlane and Thunderbird with standard or overdrive transmission.

I have a 1956 Ford Crown Vic with a 292 and Fordomatic. While this gear drive also fit the 1956 Fordomatic? If not, where would I might find a good speedometer drive gear that would fit?

Thanks in advance,

Danny
