When did Nascar teams stop using factory chassis' and started with a full racing chassis? I recently won a MPC Petty Charger on evilbay and would like to do something with the chassis but not sure if the chassis is correct or whether one from a AMT 71 Charger would be more correct.
I plan on doing this with the Petty Roadrunners that I have gotten but not sure about the Chargers after seeing the 1/16 scale ones. Should I just use the one in the kit or use a more stock appearing chassis with rollcage built on top of it? I know the "K" members in front need to be scratch built to race spec and not stock.
