These black aluminum running boards were on my 2020 Toyota Tachoma double cab for less than a year.  They measure approx 78 1/2" long and the step is 6" wide.  According to the manufacturer they were laser measured to fit 2016-2020 Toyota Tachoma double cabs.  They did fit great with no drilling.  I do have the hardware to bolt them to your truck.  Wife wanted something lower so she could step into my truck with out having to step up too high.  I paid $200.00 online for these running boards and they are in great shape.  I am asking $100.00
