Do Cup spoilers need specific boot struts?

[AUS182]

Hoping this is an easy one, I've just fitted a cup spoiler to my ff and it seems to be catching on the roof once the boot is all the way up do cups have short boot struts or have I made a boo boo when fitting it?

Thanks in advance for any answers, Mat

Cup spoiler is a straight swap, different struts needed for trophy/v6 spoiler
