I have been working on a 1962 Impala SS convertible for over 10 years now and I am a real stickler for originality right down to the Original bolts, nuts, and clips. I have several questions that maybe someone can answer. Concerning the rocker panel moldings, the 1962 reproduction clips contain just press in clips but I have a very original 1962 impala 4 door sedan that I am using for reference. It uses the 1961 style oval bolt on clips at the front and rear attaching holes. It uses the push in clips at the center locations. The 1961 style clips on the 4 door look very original with plenty of rust and the studs broke off when I tried to take them off which you would expect with an original part after 58 years. My question is which clips are correct? It looks like I have to order 1961 repop clips and 1962 repop clips to get the correct parts. And on the hockey stick molding attaching nuts the very original 1962 4 door sedan uses small metal nuts that still have original spatter paint on them but I saw an original NOS hockey in the black and yellow packaging that uses plastic nuts similar to the side molding plastic nuts only smaller. Which nuts are the correct ones used during production? Thanks for your help.
