1958 Impala with red body and white top

Bought the car recently from an 80 yr old man . I do not know much about the car other than it is in overall good condition . It has some rust issues on the areas shown in the photos . and maybe more . The trunk seems solid with some surface rust and floors also seem solid. The motor is a crate 350 and I am not sure of when it was installed but does run good. The interior is in good shape and also seems replaced within a couple of years . The rear wheel kit was also installed on this vehicle and the wheel skirts are also with it. When I bought the car it needed a master cylinder which I am in the process of replacing .
