Wheel and tire question for 68 GTS

Hey Brian:
Your correct in the number of choices and sizes. It can be overwhelming. I'm looking to get some larger rims and tires to improve the handling and ride quality of the Dart while maintain an original or day 2 look. I'm not cutting anything, they took my sawzall license away a while ago.
There is a GTS registry for 1967-1969 Dodge Dart GTS's that came from the factory with the 340, 383 or 440 engine. Interesting site with some nice cars. It's www.gtsregistry67-69.com
If that doesn't work you can google it.
