It’s been a while since this topic has come up but yes, those threads are 24 TPI. Early Fords and Johnsons used this thread size and it’s probably old ASME #14-24 or AS 1/4-24. There’s only 0.008" difference between the two so careful measuring should determine which they are. 1/4-24 thread OD is .250 while #14-24 thread OD is .242.
Taps and dies for each can be found but if you have a friend with a lathe, he should be able to make up a few screws to use with your puller.
