Default Antenna rotator

Not quite vintage but Ive a yaesu g-400 rotator with the round dial controller with an issues so Im calling on the collective

Ive noticed the antenna has gone about 90 degrees out to the controller needle position, the needle does stop a bit at a couple of points and presumably over many rotations backward and forward this hysteresis is adding up. Am I right in thinking that (for now until I can investigate) if I set the antenna position to North (reference point for the controller) then disconnect the rotator from the controller and set the controller to north, then it will all be back in sync.

Googling is pointing to the rotator pot needing changing. Ive attached images of the ones supplied by an antenna place, can I assume that the RS components pot will be a suitable alternative ?
