[PANAVIA]

Paul, I would go out and see several cars ( CSX's ) and take pictures and see what time period you want to emulate.

For me, it was the post production AC car which was a 427 chassis with a 289 in it as sold to UK buyers after the Shelby contract ended.

so in clarity , are you trying to build / emulate a 289 slabside, FIA, or 427 car >?
