'66 Barracuda 273 Commando VS '71 Charger 383

That Charger isn't an R/T or even a 500, if it is the Rallye dash, hood, doors and tail lights have been swapped out for the standard pieces. If it's an R/T the VIN will start with "WS", if it's a 500 it'll start with "WP" and standard version starts with "WH" for hardtop or "WL" for a coupe, the coupe has fixed rear windows.

That said, I'd still make the trade.
