My driver's side door sags when you open it and then when it hits a certain point you can feel it drop a little more. How much do you think a body shop would charge to fix this because I'm pretty sure I can't do it? Also, the interior door panel on the same door is coming off...how can I reattach it?

 

I used to have the same problem when I had my camaro. You have to take off the hinge and re weld it. It sucks to have that done but thats whats wrong. I never got it fixed just sold it like that.

 

You may want to check the bushings in the door hinges because they probably need to be replaced. That's not uncommon for 3rd gen f-bodies. I had several 91 camaros that did that. you probably need to take it to a body shop though. About your door pannel, go to a junk yard and look for those plastic pieces that screw into the door pannel and pop into the door. Yours may need to be replaced.
