Hi everyone. I got my first car almost two years ago: a 1983 Mustang Convertible GLX. Unfortunately, I ended up with a nasty dent in my rear left quarter panel. What are some good resources for finding this specific part? (Also looking for a trunk hinge and possible some top frame parts) My dad and I have tried pulling the dent, and it just won't come out. There's even a small hole in the middle of the dent. The car is a POS, but I love it to death.
