.... I sent a note to the customer service folks at Hasbro, hopefully they'll be able to offer some sort of solution, which will probbaly be "Ship it to us and we'll send you an equivalent item".
I've bought a dozen or so Star Wars and GI Joe vehicles in the last year or two, and they've all been complete up to now, so I can't complain too loud, just frustrated today....
I got my replacement in the mail yesterday. It was the same vehicle I sent in! Whoo hoo!! Thank you Hasbro and thanks guys for the stowage tips. I think I went a little overboard with the stickers though. It looks a bit like someone who got just one too many tattoos.
