Arrold, You're good for #9 for your Porsche.
hksk25, Welcome to the Ford-Porsche Wars proxy; you have #1
Dan, I haven't heard anyone ask for the #7 yet, but thanks for the offer in case someone who usually uses is wants it.
Docdoom, Welcome! Glad to have a Porsche 908 in the mix, but #5 is already taken (Aloha), so you'll need to choose another one. Look at the first post in this thread; about 2/3rds of the way down the post you'll find a section that says "Pre-Registration"; that's where you'll find the number that have already been taken.
