Internal Conflict! To change or not to change.

Similar questions with my 65 Dart GT. I try to do bolt-on mod.s where I can always go back to original. Maybe drill a few holes, but not hack up the inner fenders and such. My paint and body isn't original, though the color is probably close (light yellow). I must repaint since rust is showing thru some body work and the paint has runs. I am currently re-doing the interior and see repairs to both sides, both doors and quarter panels (viewed from inside), and the left strut ripped thru at one time (LCA folded back?). I will repaint light yellow, with white top between the chrome.
