Hey Jans,
I am not to sure about finding decals for 353rds "Alabama Rammer Jammer" but I do know that Aero Master did do "Double Nuts" from the 325th.
If I'm not mistaken they are now out of production but you may still find them here, evilbay or at your local IPMS show. Heck your local hobby shop may even have a set hiding somewhere?
One of Hasegawas many releases of the 1/48th Stang, they featured decals for "Double Nuts".
Good luck my friend!!
Flaps up, Mike
If you would listen to everybody about the inaccuracies, most of the kits on your shelf would not have been built Too Close For Guns, Switching To Finger
