CosmicSpore, welcome to MW!
Now when you say Max Special, that's the DYRL version, right? The Hasegawa VF-1 kits have spare blue decals, but I'm not sure if that's what you're after - or even if they'd properly fit a Bandai kit.
And from what I saw, the 1/72 variable reissue was solely the VF-1A (which I already have! bummer!).
HEWAT = strike parts?
Finally, evilBay is probably you best bet. The 1/100 kits aren't terribly popular these days so you can pick them up reasonably cheaply. A variable 1/72 Max special might be a little harder to find. The re-issue VF-1A is probably the best option - if you start a request thread you can prob grab a hi-res scan of the 1/72 decals from a MWer and print your own.
FWIW
Again, welcome!
