I haven't seen this one in person, but I would back the tractor up to it and see if it will fit. Since the 2/8/9N set the standards for cat1, you may find it fits pretty easy to your rig.
I am thinking that the 2/8/9N Ford had a different pto spline count (6 versus 8?), so you may need an adapter (easy to get). I have an F7, which the current F8 is slightly different (lots of guards on the shaft, different pinion shaft). They used grease instead of oil in the F7 & 8. No idea on the earlier models.
On the PTO drive shaft, make sure it still telescopes in and out. If it doesn't, look at the cost for a new one before investing much time into it (though this unit is likely worth replacing it). You can get a new splined yoke end (take off the U joint and it replaces one 'U' end).
Have fun!
