t is not. Cable driving proofmeter turns slower on NAA than on 8N, so 8N proofmeter installed on NAA will read only 64% of actual rpm.

As JMOR said, they are not the same.
8N runs off the governor, NAA off the hydraulic pump.

I grabbed one off the pegboard out here and installed it.
Didn't pay attention to the part number. Different speeds.
