I have a 1969 that I'm restoring and it has side pipes. The black fiber glass piece that runs the length of the sidepipe cover that you attach to the corvette appears to be obout one inch short front and back,expossing the lower body of the corvette. They do not appear to be broken off. My questions are is this normal. Also I know 1969 had both a lower and upper rocker panel. Possibly should there be a upper or the smaller rocker panel on the car before you attch the side pipe covers. Thanks Rick
