Strut problem?

[Pinchlite]

I have 2 new kyb struts in front of me ready to go on.

I got tire off and see the rubber bellow is torn.

I talked to KYN directly and they said there is a piece that needs to be cut out and reused or put new one in.

It seperates metal on metal contact.

I was going to get these but he said it may not work.

Does anyone here changed strut on 2007 yaris Hb 2 DR.

I am confused as to what this plastic piece is that he says needs to be cut and reused or buy another as its part of the strut assembly.

From what he described its a hard plastic piece connected to the bellow.

I do not believe he is talking about the plastic piece that goes between shock and round metal cups on top/bottom of strut.

Here are the struts that I have
