Cat 966C or 950 Steering question, wheel turns right to left

Anyone out there have one of the above or even a 42H 980 or 87A 988?

Trying to find out the number of turns for steering wheel to go from lock to lock, full left to full right turn.

All the above appear to use the same internal steering gear parts so I'm thinking they should all have the same number of turns.
