Question on e36 abs sensor on 325is

[dimilo]

Hi guys,

I recently bought abs sensors from Pelican for my 1994 bmw 325is. My sensors were stuck so I had to disassemble the front hubs in order to punch them out from the front. After getting them out, I noticed the sensors had a cylindrical metal casing that the sensor fit into. The new sensor doesn't fit into the casing,so do I need to remove the metal casing as well and then fit the new sensor?

The current sensor has a part number of 34521163028, which I can only find used sensors with that number.

I ordered this part to replace it
