Hi, I just registered here because I saw the pictures you posted here: https://www.hotrodders.com/forum/pict...or-299714.html
Do you have any other pictures of the door wood repair you would be willing to post? I am rebuilding back doors on a 36 Pontiac sedan and the wood is too far gone to pattern. The construction of your Buick is very similar. The pictures you already posted answered a bunch of questions about the curved piece, and how it attaches to the hinge pillar, but only the top half is shown.
I am especially interested in how the original wood fit together at the bottom of the door. I know there was a flat kickboard but am not sure if there was another piece in the bottom. I dont what the bottom of the curved piece or the lock pillar looked like.
If you have any more pictures of that old wood, it would be really helpful.
