I can forward you a membership application to the Ponca City Rifle and Pistol Club at your convience.
April 4 the CMP is putting on a service rifle match at the OKC Gun Club. They will have a trailer there with guns for sale to take home. I'm thinking I read you can qualify to buy one, by registering and shooting a match that day.
I don't have a clue what grade of rifles will be available, and its a limited quantity. I want one just like your after, but I'm not sure my work schedule will let me get to OKC that day to pick out the one I like. Some digging around on the CMP site might get some insite to this.
You may already know this, but most factory 30-06 is not recomended to be fired in the Garand. The rifle was not designed for the higher pressures of some modern ammo. Hornady puts out a line of ammo designed for the Garand, unless you reload, then this is a mute point,
