68 Dodge Dart

LL21B8B
Low Line Sedan(post car) with slant six original.
Door problem is probably a hinge pin or two, maybe some bushings to make it right.
Fender might need an experienced bodyman to handle that crease. 68 fenders are different from most other years because of the headlight placement and side marker.

Make it safe to drive and dependable, then add on the goodies.
Good luck!
