If you want to stay with the '67 lockstrip for the rear you can buy them from YO and probably other venders. Then gently heat and shape the ones for the curved section. Hair dryer or heat gun with low heat settings and lots of patience. I did it years ago and got one perfect, broke the other. Fortunately I found an NOS one at Englishtown swap meet, saving me the neccesity of buying another set and making another attempt. I bought the repop from Mitchell's - yea - the Frank Mitchell because he was the first and for a while only vender with the correct lockstrip.
