<VV> Late rocker trim

[PETER INMAN]

Its close to time to put my car back together. I purchased our 65 Coupe totally disasembled so I dont know how things looked before disasembly. My question is the rocker trim I have has a bow or about a 3 inch arch from end to end. Im assuming this is the way the pieces were made to help keep them straight after assembly, am I correct? Thanks to anyone who can tell me.
