Just to be clear, I don't think a stock-ish (the later ones had no true stock option) '66-'69 Falcon would be that big a seller. But it the drag front end setup and Webers were brought back to the chrome tree it would add some value for not too much effort. That original kit had one surprising detail - look at the instrument cluster with a magnifying glass and you can read the odometer! (it shows 000000)
Frankly, to me anyway, the only potential retool/clone Falcon that would be successful would be the '63 Futura - IF it were a hardtop Sprint for the first time.
