Dave, when this sim affords you only limited options, you have to get creative... which you have artfully accomplished here. In my opinion, the Fords and Mercuries look fine on the Charger bodies. Is it perfect? No, but it's pretty darned good.
As for skill rating the 1971 cars as a prerequisite before releasing them, I wouldn't worry too much about that. Most people have their own preferred methods for skill rating car sets and any ratings that the cars may have when you do release them will likely be changed by the end users anyway. That being said, I personally rate my car sets using the NRatings program with comes with several different formulas to try. If you were to choose using the NRatings method, I know that data for the 1971 Cup Season is available to accurately rate your cars.
If you are unfamiliar with NRatings or for some reason cannot use it, I would be more than happy to help you with that as I have assisted several other skilled painters who have created historic NASCAR car sets for release to the NR2003 community.
Either way, you are doing an awesome job recreating these great nostalgic schemes. Keep up the great work! You'd be surprised at the sizeable, dedicated and loyal following who are anxiously awaiting the release of these cars!
