We've designed our buggies to have parts and components that are easily replaced by simply undoing a few screws or nuts and bolts here and there.
Most of them are quite generic and easily sourced from your local hardware store.
Use the guide below to find the screw or nut and bolt you need. If you are a little nervous about asking for the correct size, just find your local hardware store assistant and say "hello, I need an M5x30 bolt and nut to fit please"...easy as that.
