I believe 65/66 Darts are the same and 65/66 Valiants are the same but different from each other

65-66 dart to dart, 65-66 valiant to valiant. but you can use the front header section and the 1st bow on either valiant or dart. the second and rear bow are again dart to dart and valiant to valiant.
don't have a 63 or 64 valiant or dart handy to check if they are the same.
