I'm talking about the whole trunk. Look at your friends car closely and you'll notice that the 95+ trunks are curved in the bottom corners. If you were to put the new lights without changing the trunk you would either not be able to close the trunk or brake the lights trying.

Personally, I was thinking of doing the conversion to my 94 S420, but decided not to because of the high cost ($1000+). Plus, it's not something that many people even notice.
