Help, how many types of radar are there before 2021 S60/v60?

[hao166]

I want to add front bumper radar and front and rear side radar to my 2021 S60. Upon inquiry, it is found that the 2021 S60 front radar has four part numbers, namely, 32209487, 32209488, 32209357 and 32209358. Two shapes, straight and curved. Among them, the part numbers of 32209357 and 32209358 are also the part numbers of the radar on the 2021 S60 rear bumper. I took apart the rear bumper this afternoon and saw a radar. The part number on the left outside is 32209857. Is the query result of this website correct?Https://Sweden-parts.pl/wspomaganie-park...S60-21-spa Has anyone ever installed or dismantled his car? Does the front radar have four different part numbers? Or two identical part numbers. Thank you.
