Im starting to restore a 73 mustang convertible that i have had since i was a teen ager now im in my 40's and the car has sit in a building for around 20 years,The car is all original even the aluminum wheels,And It also is what they call a Q-code car with electric windows and air and deluxe interior,so I dont want to let it rot away.But i noticed the passenger door is rusted out bad in the front bottom corner and I found a 73 coupe thats not that bad and wondering if alot of the body parts would interchange.
