Gasket no, Trim moldings yes!
If your going with the 67 style, I've got an extra 4 door gasket for sale but you should try to save yours.
New 68 style gasket should be easier to find for 2 door.
PM sent with all info and phone numbers on suppliers!

Oh forgot you have 2 door no post, everybody and their brother should have your gasket. Shop around with the numbers I sent you. Most of them should have your new gasket. Just tell them the style you want.
