Buick 1928 Standard Six two doors model inside repair

[RUDDY]

Dear forumers! I am trying to disassemble the passenger compartment of a 1928 Buick Standard Six two-door model. There is an elbow on the inside rear window trim. How do I remove it? I hope someone can help.

I will post a picture of the current state later. Thanks

Use a needle to probe the seam line around the lower edge for gaps just big enough to allow a screwdriver to fit. Just guessing there will be 2 wood screws angled upward that attach the elbow rest.

Not quite sure what you are calling the elbow but I assume it's the corner piece.  You first need to remove the seat cushions.  Seat bottom comes first. I don't remember how it is held, but I think it is just a push back and pull up type of fix. (Yes I have removed them but it's a long time ago) Others will have more recent memories.

Hi Oldtech and Oregon Desert, thank you both for the useful information.
I will post pictures of the work later.
