challenger doors

Need some advice!

I have the opportunity to pick up a set of challenger doors and I have no idea what they are worth, or how to tell if they are oem or aftermarket.

Are std doors 1970-to74 alike! what are changes for upgrades on performance model such as R/T models, just skins.? electricwindows,etc

They are shells with handles, no glass or regulators,they are straight and had been primed but need a little cleanup- otherwise solid metal doors from Texas. Reliable source.

I do not have pics but can get in near future (yes I have seen them)

I look forward to, and appreciate all input
