==64 Valiant/'Cuda interest. VEGAS.

You have found a unique site that can answer many questiions you might have. Sure is a big difference in the size of cars you are looking at and leaving!! Early A-bodies are cool but second gen are better due to the variety of engines that can be installed. Just my 2 cents!
Wheels can be a pain! First gen have a small 5 on 4" bolt pattern. 2nd gen have both 5 on 4" and 4.5" both will interchange on second gen. Not sure about 1st gen as I only had a 65 Barracuda with a 273 in it. Was a blast to drive though! Again, welcome! Enjoy your time here.
