Complete door shown is a 1967 door. The upper attach point at the division post is different on the 67. It also has the countersunk hole and chrome screw. 68-72 did away with that. I have a 68-72 vent window. In 1969 to72 they moved the lock knob forward. Heres pic of 67 door, and both sides of a 69 door upper inner structure. Most of the stamping for both is the same. The exceptions are the division post mounting bracket, hole for division post screw. lock knob hole location, lock knob bracket for the linkages inside, and the change in the stamping to locate the linkages. My intent is to use clecos to line up the trim screw holes, then cut through both pieces below them, this way I have a good weld joint. Then use buttweld clamps to keep the spacing correct.
An alternate would be to move the lock button hole, and weld up the old one. Cut and position the small section that works the linkage. Swap out the bracket that holds the 67 division post with the later one. Drill new hole for 68 up division post. Fill in the 67 only division post screw hole.
Both ways have their pluses and minuses. Pics with red line drawn on them would be the extreme method I was looking at originally. I may just do hole cut and move brackets around method.
