T&T blanks can be gotten from any T&T dealer. Dealers rarely have them in stock though it should only take a T&T deatler about 2 weeks to get a 2-hander blank from T&T. There are several T&T dealers that are advertisers of the forum, and all of them are good, honest, and reliable folks. Contact one of them and have them get the T&T 2-hand blanks you want.
The only way you can get a GLX blank anymore is getting lucky and finding someone who has an unsold one laying around. Otherwise, you are out of luck with the GLX 2-hand blanks.
