Anyone know where to get replacement floor pans for my Hilux?

 

not available .. you will need to make your own

 

Take some measurements and go to a pick n pull and cut some out of another car. Some people also used to use the sides of old dryers (appliances) because there is usually a bead running through them for strength. I haven't even seen floor pans sold for newer Toyotas. Pans for old Mustangs are available but I'm not sure if they'd work well.
