This special rubber profile was designed after a NOS sample. Used on Split Window Beetles only you will not be able to find this rare profile anywhere else. Remember that other cheaper rubber will not fit correctly in your Split Beetle metal channels making your glasses rattle or not even move at all! Correct felt material included. Enough for both channels. The 49-52 style consists of 2 different rubber profiles, while the version which was used up to 1949 used one single profile. Please indicate which style you need in the box below so we can send you the right one!
