Cut out my old floor and had this one in the car in 28-working-hours. Smooth Sailing! My old floor and frame rails were GONE! This floor fit PERFECTLY and was honestly way easier of a process than I initially thought! Now I have a great base to finish the rest of the work on my car. Highly Highly Highly reccommend this floor if your car was like this one of mine and sat in a field for YEARS and had its bottom rot out.
