I decided to replace the severely weathered front windshield locking strip on my 84 318i. I sourced a strip from an overseas vendor which arrived out of its original BMW packaging. As I was having a chip repaired on my windshield I asked the glass shop to install the strip. They were hesitant since the new strip seemed to be about 3/32” wider. The new strip has a flatter profile then the original strip which is rounder. I thought maybe I was sent a 5 series strip which is wider, so I ordered a new strip from a US source which arrived in factory packaging (51311884402) and it is identical to the other new strip. Is the original strip distorted/shrunk from 38 years of sun exposure? Are the new strips wider than the original? Any thoughts?
