I havent gotten an invoice yet, but AFAIK, the 2 rail F-3's have arrived at MTH and will be shipping out to us later this week.
I'll be sending out Invoices for pre-orders shortly, and then putting extras up for sale on the website.
FWIW...There are no extras at MTH at this time. I did order some extras, so hopefully we will get all that we ordered, and have a few extras for sale.
