Before anything else is said I’m exactly per se a classic bowtie guy I’ve spent most of my time dealing with 40’- 2000 Fords and early 80-90 molar , I recently acquired a 77 Camaro that has been under a tarp since 2009 no idea what abuses the body has seen before that I am fully aware of the hinge and door sag issue that comes with these cars due to the length and weight of the doors all old 70s rigs share the same issue my problem is the passenger door on my vehicle will not open regardless of what I try kind of stuck here could use a hand thank you

 

can you get the door panel off? linkage may have fallen off.

 

This is my next step , and was thinking of it as I posted this lol
