Just to make sure I was clear about what I needed: I just need the little chrome trim piece that is attached (glued I think) to the passenger compartment side of the armrest base. About 6 inches long. Now, that posting on the arm rest backing plates was very informative and thanks for letting me in on that little scam. My 68 convertible appears to have the correct backing plates thankfully. In fact my car is very complete but unfortunately, the last restoration was about 20 years agao, and it has passed from a caring father to a negletful son, prior to my saving it. This means that it needs another full resto.
