[Brakes] ABS sensor bolt size [or part number]

[Multispacer]

Hello, I've got an ABS fault light up and had it scanned by my local independent Citroen place who advised it it was the front n/s sensor. Had a quick try to get it out today in between the downpours but it's rock solid so might have to drill/easy-out it out. Anyone got either the part number of the bolt size, so I can get a replacement before I attempt to get the old one out? Thanks.
