does RB67's rotating adapter have a pin sticking out on its lower right side?

I had an RB67 Pro body and a 120 back(but without the rotating adapter) and finally bought the adapter.
The adapter was for Pro-s but KEH website said it's compatible with non-S bodies.
Today I'm putting it all together but the Pro-S rotating adapter has two pins sticking toward the body side.
I had to remove one of the pins just to be able to mount the Pro-S adapter to the Pro body.
The second pin, which matches to a hole on the lower right corner of the body, seems to be the problem.

Do RB67 Pro rotating adapters have this pin sticking out toward the body?
If so, maybe its shorter than that of Pro-S rotating adapters?
If the rotating adapters for RB67s don't have this pin, I thought I'd just cut it or pluck it out

I have both the Pro and ProS adapters here. Both have this pin but the one on the ProS is longer and doesn't push in flush to the adapter which may keep it from mounting properly to the Pro body. The pin on the Pro adapter sticks out 4mm at rest, the ProS sticks out 6mm. If you cant get a Pro adapter then instead of cutting the ProS pin off completely I'd just shorten it to match the Pro adapters 4mm pin.
