OK, I am new here. I am doing a mustang coupe to fastback conversion. ( Yes I now some of you think you can buy a nice fastback for 10K. I do all my own work and plan to have this car done all but paint for 6500.)If you think it is a bad idea please keep it to your self. Now that were past that. I have a 66 coupe that a tree fell on the roof and caved it in. I have a old Fast back roof. Going to mate them. I was going to install skins but think I need full quarters. I see 2 piece and one piece listed at most vendors. I really dont need the sail panels. SO other than sail panels are they the same? I have been gathering parts and ready to start. Dont want to pay 400 for a quarter if the 200 dollar one work just fine. This is a project for my 17 year old son and my self. Which one ones did you use?
