My 74 Z came with rocker moldings. Not on it, the previous owner gave me a pair of wide moldings when I bought the car. Not sure if they belong. How can I find out if my car had rocker moldings when born? I don't have a build sheet. Were they a standalone option or part of a style package that I might have other parts of? I don't know how they mount but assume a telltale sign would be holes down the rocker panel but mine are solid. The car was painted at one point so they could be filled.
