Yeah, I was going to post a thread on this a couple weeks ago (on Redwolf looking at PTW stuff) but I didn't know that they were new or not. You can always try a Ragis LasVegas restricted order to get some in. May take 6 months but they will get in eventually...
That or you can ask Redwolf to remove the fake plates from the mag and put them in the parcel seperately. Since they are only one sided plastic plates (at least the G36 ones were for much of the piece) you may get them through will only a little paper work. That or leave them out entirely, mag will still work, just needs some padding.
