The kyb boot is different then stock. I believe the original snapped to the top spring support. The kyb sits in the top support but would fall, the bottom of the boot is too loose.

Have any of you guys replaced the strut boot? Would like to see the setup.

I threw them in the bin... there are many cars driving without these ..   anyway the lower part is always wider thats normal there is no need to put a clamp on there..  it can stay open.

I just put one of my 240 struts together using the KYB stuff. I did just like you show in your picture. I figure when its under load it will be about right. I would have no problem just leaving them off.
