Part number changed 3/69 and 7/71. Not sure the 3/69 change but the 7/71 was a complete change on the windows in the hard top. The pre 7/71 I show NLA. To use the newer weatherstripping you need to change the glass also.
For a 68, the only continuous seal you can get is the windshield, all other hardtop continuous seals are no longer available. However, I went with CCOT, they have the correct cross section. Just cut approximately 1/4 to 1/2” longer...and use a little 3m weather seal adhesive.....,.and as the great Gonzo stated on Sesame St.....”No one will ever know”
Mark Jennings response is exactly what I’m about to try. I have a 2/71 (feb/1971) and they don’t make the rear hatch seal anymore. Found a nearly identical piece online that I am going to cut and use 3m super black to make a continuous piece and see how it works out.
