[TenTec] O-II Encoder Part?

[Bernie Skoch]

I have decided it's time to replace the digital encoders on my Orion II.
I found an article on-line describing replacing the Orion I encoders, with a reference to this part:

Does anyone know if the encoders in the Orion II are the same ones used in the Orion I?
Thanks & 73,
