I need help with sportsline springs

i've had eibach sportsline springs installed a little over a week now,well today i went to my local dealership to get my steeda cc plates installed along with a 4 wheel alinement.after they looked at my car they said they could do the alinement without the cc plates. they ended up doing the alinement and i still have the cc plates in the box they came in.my question is this possible,everbody i've talked to in here says the cc plates were a must with sportslines.but i would think if a ford tech. said my car was alined then it must be.now i don't know what to do.keep the cc plates for a while to make sure or send them back and get my money back.
