The Group Buy price is $720 for the AMS hood, and $50 shipping to anywhere in Southern California. The vendor handling the group buy is Ultimate Motor X. They can be verified on this site and with VIS Racing. We've done a previous group buy with them that everyone was more than happy with. And, this group buy actually got fulfilled on Friday, but I'm sure the vendor can add on another purchase.
If you're interested, send me your e-mail address and I'll have the vendor prepare an invoice and I'll forward to you. The payment can be made via Paypal or Credit Card. Indicate if you need to pay by Credit Card so I'll include that form in the e-mail.
