That's a nice looking truck, I'd like to see under the hood.
The Mitty is a three day event. Folks from Garage Zero and the Georgia Z club will have a place in the infield you can join them at. The years to go for Japanese were the last two years, Datsun and Mazda were the featured marques but there is still a nice turnout from the Datsun and Mazda camps. RA is an awesome venue too, a really nice track and nice facilities.
If you're looking to go deeper into debt, there's a 1600 or 2000 roadster sitting at a body shop/salvage yard next to 247 halfway to Macon. The body and interior are likely shot but I think the drivetrain could be salvaged, who knows. I'm not a roadster guy or I would have shaken the tree a little harder but those things are getting rarer and rarer to find.
