2007 Toyota Tacoma , I used some stainless steel security bolts instead of the basic zinc hex bolts that were included to prevent them from rusting and any punk with a pair of pliers could probably remove and run off with them , also I drilled a couple of small holes in the bottom of step because if any water gets inside and it can there's no where for it to drain, I can step in and out without the steps but it looks more bitchin with them there than without
