Should I replace the doors?

[tdp67]

Just wondering what it would cost to replace the doors on the 67 before I paint the truck. I am seeing some rust flakes coming from the inside at the weep holes on the front of the under side of both doors. In fact they were clogged a bit til I unclogged them with a key. The wing window on the pass side is not from a 67 and is dinged a bit. The rubber needs to be re-done on both. I am seeing a little bubbling on the bottom rear corner on the drivers side door under the current repaint. The window is a little rough rolling up and down on the drivers door. Is it worth the investment in new doors before a nice paint job? Where would I find them at a decent price?
