T98 speedo gear question
OK so I'm getting to put the engine and trans in my '59. First I'd like to get close to the right speedo gear/s in it before the big stab. 3.50 rear gears, 29.5" tire height. I know the driven speedo gear is 19 teeth and I'd like to avoid taking the back of the trans apart to count teeth on the drive gear. Is this a question for numbers dummy? Thanks

1959. Could be a cast iron DRIVEN gear, or a fibre DRIVEN gear riveted onto the end of a steel shaft.
Look closely at the original, it should an ID number stamped on it.
Once I know which DRIVEN gear is has, I can figure out the DRIVE gear.

01T, cannot be 71, will be 17 (271)-B
Could be just 01T-B.
If 8 was marked on DRIVEN gear, it would have nothing to do with DRIVE gear teeth, because what DRIVE/DRIVEN gears truck has, depends on trans type, rear axle ratio and original bias ply tire sizes.
1964 F100 2WD 3.70-1 4 M/T 7.00-15 tires: B9C-17285-A 7T DRIVE gear / 01T-17271-B 19T DRIVEN gear
1964 F250 2WD 4.56-1 4 M/T 6.50-16 tires: 01T-17285-B 6T DRIVE gear / 01T-17271-B 19T DRIVEN gear.
How many more examples would'ja like? There are pages of like examples for F100/350's, P350/500's, F500/600's and etc etc etc!

ND, sorry for the confusion. Both my trannies are for an F350. I pulled the other driven gear and it reads as follows:
01T-71
E22
The first one is a 19T gear and the one in front of me is a 22.
This is the main reason I don't want to pull the drive gear out. I don't have a socket, impact wrench or compressor that will break the big nut off to pull it out.
