IRI Teams with a spare P60 gearbox?

I understand that the 5:1 stage requires a specific carrier plate (and planet gears), but are you saying that the 4:1 sun gear can not be pressed into every variety of carrier plate that accommodates the previous 5:1 stage? There's a different carrier plate for pressing in a 5:1 sun gear vs. a 4:1 sun gear? That would be absurd. Why not have the 5:1 sun gear and the 4:1 sun gear with the same press fit geometry?

Yes, I am saying that. I don't have access to the gearboxes until I get to our shop tonight to confirm, but I believe the carrier plates are different between the two. From what I recall, the sun gear in a carrier plate fits into a broached hole with the same number of teeth as the sun gear.
