your 69 grill won't work on that grill opening. looks like the whole front clip was changed to later model that uses a different hood and (i think) fenders. You've also got a 67-69 dart bumper on there. I'd leave it like it is until you can find the right hood, bumper etc., it really doesn't look bad the way it is.
as for door glass, the Dart four door glass won't fit but the 67-68 Dart two door sedan (post) cars use identical doors as the 67-72 valiants, keep an eye out in the for sale forums.

after a closer looksee it appears that the fenders are correct and will work with the 69 grill, hood is different though. -pauly
