Does anyone know t98(1960) PTO gear direction? If I got the 6 hole access door off, would the gear spin up or down?

 

Thats easy with truck in neutral have some body turn engine over while you watch it.
just take the coil wire off so it don't start. Usually on the smaller PTOs, should have two
shafts that turn oposite so you choose the direction you need. Nothing can be done
with the rotation of the tranny counter shaft - direction is determined by the PTO:

 

The gear rotates down if you are looking into access cover
