any insight on what size the rear tires are, and what front tires you SS/AH guys are running?

we have 15x33's under our 67, and some moroso 7.10x15's up front. i love the way the front tires fill the fenders up. if anyone knows about that kind of stuff, like cage, chassis, tire size, any of that, let me know, id like to build ours to resemble a SS/AH car, and run like one too haha.

another side question, would my 67 be legal, ever, or is this class for the '68 cars only? im guessing its for '68 cars, but, i could be wrong.

thanks
