ARB air lockers RRC

I'm looking to purchase ARB air lockers for my 1994 Range Rover. ARB offers 3 types of lockers: 10 spline axle shaft, 24 spline axle shaft, & 24 splint with traction control. My RRC is definitely 24 spline & does have traction control. My concern is that ARB describes the traction control model as for the P38A, so now I'm not sure which lockers model to get! Is it strange that a Range Rover Classic has TC, which is usually found in the P38A?
I'd really appreciate all feedback

you would want the 24 spline one,rrc diffs are either 10 or 24 spline,p38 diff wont fit,having t/c or not wont effect that

Is it common for a RRC to have TC? So the ARB 24-spline locker would fit a 24-spline RRC regardless it has TC or not?
Thank you

yes t/c has no effect on which air locker, as when locked both wheels will turn the same
