New LS1 Owners - Newbie Tech - 98 ls1 no frc's??

So I called a couple places that said they do custom ready to go fuel rail covers. I was already to purchase a set but when they asked me the year of the car and I told them they said that the covers dont snap on to the 98 ls1 because the coil packs are different and the valvecovers also bolt on different..

Is this true? Anybody out there have a 98 camaro or firebird with frc's?

Yep different valve cover.
