The difference between Skullcap mirrors?

[mikegale64]

Hi, I have a 2002 CDT Tourer in need of a chrome skullcap cover, I've stalled because I'm seeing there are different varieties listed online. Ive looked underneath for a part number and it seems to me like its E 015432.
Can anyone please shed some light on this for me please?

two types of cover for the two types of mirrors and that's it.skulls on the later ones or bullets on the early ones

The bullet type is on the left and the skull cap type on the right. ;)
