Rear Window trim moulding for a 68 Notchback

All I have is info that may help. 68 and up had a stainless trim (reveal moulding) that was held on with clips. That rubber gasket had lips that fold and interlock. If you have the 67 type gasket you could put a round lock cord in it after you install the clips for the trim but... that gasket has a taller profile. The stainless trim doesn't lay over it right. You may get a wind noise (whistle).
Same details apply to the front gaskets and trim.
The only difference in trim for 4 door a-body windshiled moulding through 76 model is the A-pillar sticks are 2 inches longer. Easy enough to chop off for 2 door model use. Good luck.
