I have a pair of original black Madrid grain vinyl sunshades (i.e., sun visors) on my 68 Camaro convertible. Recently, I came into possession of another pair of original 68 (or 67?) convertible black sunshades that I was intending on restoring for another person's car. What piqued my interest was the shape of the vinyl piping clips on the pair that I just acquired. The sunshades on my car have the same shape chrome-plated steel clips on the vinyl piping both inboard (i.e., by the inside rear view mirror support) and outboard (i.e., by the sunshade support assembly). All of the clips were magnetic and appear to be stainless steel, not chromed steel. Some stainless steel is magnetic so it is not a defining method to rule it out. The other pair needing to be restored have the same inboard vinyl piping clips as on my car; however, the other pair have rectangular vinyl piping clips on the outboard side. Attached, are photos of the two different piping clips on the other sunshades needing restoration.
The black convertible sunshades appear to be the same [see reference #1] in both 1967 and 1968 model years as part number 7666122 under Group 10.203.
I guess it's possible that there were two different manufacturers of the sunshades or the clips changed between 1967 and 1968 model years even though the part number remained the same? Does anybody know definitively which vinyl piping clips are factory correct and are they stainless steel or chromed steel?
