Thanks for the info as that is the part # I had listed as well. Though I am not convinced that it is correct.
The reason is that I have an NOS pair of the 3579148 rocker mouldings still in the package and when compared to the original mouldings they are noticeably different on the ends. The originals have a more defined sharp spear shape point at each end and the NOS parts are more rounded. The length measurements are the same it's just the ends that are different.
Any additional thoughts ???
