4 Pack 4040 1515 T Slots Aluminum Profile Door Hinges | Zinc Alloy, Slotted Hole

I looked into this bracket and you would be sitting very very high. It'll be like a bus simulator position rather than race car, lol. I used these hinges for front https://a.co/d/08PcA5lB Some washers in between them and bolt to mount 2 hinges to each other. I had these hinges in the back https://a.co/d/0guulKwg So the process is you remove the slider from the seat, mount onto rig, mount hinges onto slider, mount seat on top with M8 or M5 bolts (can't remember), adjust amount of washer between front hinges for desired angle.
