Rear Beam Swap - North Herts

[C.A.R.]

Rear beam now almost fully stripped, but having a 'mare with the ABS sensors. What's he best way to get them out? I've removed the bolt already, but the sensors won't budge. Part of me says to just leave them on there and plug them in when I swap the beam onto the car - but one of them has snapped where the cable starts anyway so I'm not sure that will even work! Looking at it they just seem to be wedged through a hole? Can't tap them out from the other side as I've got no leverage.

Concerned even more that the ones on the car currently might be similarly stuck!
