67-9 cuda door repair questions

Sounds similar to what I have planned Matt. My 69 vert door(white) is complete(less door latch, one on the way tho). One difference with the 69 vert is the wider inside cat whisker. I would assume that they mount the same as on 67 door? I havent removed either pieces yet. Last thing I need is more shrapnel laying all over the place lol.
For your #3&4 points above, I'm not sure where you mean to cut/weld upper inside of door? I'll post more pics in a bit.
Heres the game plan, I have a 68-72 vent window assembly, I also have a 69-72 latch assembly. If it's a coupe without wide window lower opening trim, then weld up the trim holes. I also have the top inside sheetmetal of a 69 barracuda door including the linkage, and section of the door where the linkage mounts, and its cut below the upper door card stainless trim. If you trim it right, you can hide most of the seam under weatherstrip and the door card. Heres where the actual door modding comes in.
  1. Weld up the vent flap on bottom of the door
  2. Weld up the vent flap on the front of the door
  3. Remove 67 upper inside of the door
  4. Weld on the 69 upper inside of the door
A 69-72 dart 2 door inside door top sheetmetal is the same in this area and can be used for the door mod.
