The plan is to add this to the 5 feet mini, but if you want to use it stand alone, cut off about 15 cm from the underside of the plan. and look how it's done with the 5 feet quarter. this is a double coping spine, so more for oversite grinding and stuff, for more tyretap tricks go with the street spine, if skateboarders also will ride the ramp, use this.
