B body interchange question.

Convert a Charger to a Roadrunner?
That's like trading a $1000 dollar bill for a $100 cuz you dont like the color....
Well I was hoping that it could be a clean basis for a roadrunner cloning, but obviously not. I was hoping that there would be more interchangeablity like with A bodies. There's some pretty obvious differences, but it's hard to tell for sure until you get your hands on it.

Not being a Charger fan removes emotion from the decision making process. It'll be based on pure ability to flip the car. If the numbers don't make sense to me I'll pass it along to you guys. Of course it could still go sideways. The guy may decide he's going to restore it after tripping over it for 4 decades.
