I can't speak for Tiger usage, but my recollection is that most
Ford speedo gears have left pitch. The one in my T-10 does.
What I was told was that the pitch reference was from the cable end
of the gear. If the teeth angle to the right then it's a right pitch
gear, etc.
I believe the gear in my speedo has 16 teeth. It reads about 5 mhp
at 70, but I suspect that's has more to do with the low profile tires
on my car rather than the wrong gear.
BTW, I bought my gear from a local vintage Mustang shop. You can
order than from Ford, but a lot of the Mustang places have them in
stock. Also I didn't need a Ford part number, only the number of
teeth and the pitch direction. They're cheap enough so you can
buy one each if your not sure. This place I bought mine offered to
let me exchange it for if it wasn't the right one- as long as it wasn't
damaged.
