The glass channel run for the rear lockstrip for the 66 and 67 hardtops and convertibles is an entirely different profile as compared to the sedans and wagon applications. At the current time, the profile for the 66 and 67 hardtops and convertibles is no longer available as we were able to source this piece from the original OEM vendor and they had no desire to continue the product. For the sedans and wagons, the glass run channel extends down into the door frame for both the front and rear doors. The division bar channel run is a different profile as well so that it fits snugly into the channel. No quarter glass seal for the wagons or sedans. Have to take into consideration that 63 to 65, 66 to 67 and 68 to 70 all have different profiles, attaching points, etc. Most all of the components are available for the different year ranges, just need to be aware of your needs.
