You dont need to tell them anything', Don't worry about it. But if you are running a front sway bar you will need spacers.

 

Take it from me buddy, you DO need to tell them what car it is going in. I only spent a month mailing stuff back and forth with them trying to get it right. They make the kit to fit all LT1's, not just the Fbody. For our cars if you are running a front swaybar you will need spacers. My trans lines also hit the alternator so you may or may not need to bend your lines or run new lines.
