EP can have the lights removed- I think you can leave one open for air intake but the other should be covered (there are headlight covers out there). no holes in the hood so you'll still need to fix that. wipers and ETC are open in Prod as well.

Prod doesn't need a dash either.

If you want to get the car on track ASAP, you could run it in ITEZ or something so you can at least run, then swap/add parts as needed to make it legal for the class you choose.

ITEZ and ITE are simply "run what you brung, as long as it passes safety rules" classes.
