Chevrolet Performance LSX Challenge Series and LSX Shootout - NMCA question?

I have a question about NMCA Late Model EFI? I wanna run in the Late Model EFI at Milan Dragway this summer. I saw in the rules that you have to have a permanent # displayed on the car. I don't have a # that I use for every race, or that is displayed permanently on the car. I was wondering what I would do for that race. Also do you need a permanent # displayed for the Rumble (index) class for the LSX shootout? Thanks!

when you register for the race and become a member of the NMCA, they'll assign you a permanent number for that year. Upon giving you that number, you'll have to pay ~20 bucks for a set of numbers for the car, after you're done, you can scrape them off

Thanks man, much apprecieated
