Windshield locking strips fro 1967 Dart

Hi i want to replace the winshiels in a 67 Dart only to find out i require a plastic locking strips. These strips go in after the windshield is installed to push out on the rubbers and stop leaking.
Two questiond do you know where i can buy the locking strips,possibly in Canada mopar dealers dont list them any more.
The other question is the 1967 winshield diffrent fron the 68-69 windshiels. If the are the same then it is just the rubber mounting hardware and the locking strips that is diffrent for 67. Can i buy a rubber mounting hardware kit for a 68 or 69 without the mounting strips and go that route with my 67 Dart.
