You will be better off to order 68 gaskets and find the stainless trim for the 67 from a 68 cuda. Im getting rid of the push in type gaskets therefore I won't need the lockstrip... you have to have the special corners to the lockstrip. I cut mine on a 45 degree until I finally got everything to convert it over to a 68. I lucked up and found the stainless trim for $120 from a member on here. The front windshield stainless trim is easier to find than the rear.
