Couldn't find a starting gate so I made one from scratch. Used small magnet to hold up lever and easily release. The 2 track pegs insert to the bottom of the track portion and when everything it put together they prevent the lever from moving side to side. super glued the box together. Track has connector inserts on each side for clamp and is slightly longer than the straight track i have to for floor height adjustments. Might make adjustments later but works well currently. Tweaked the design to fit more car sizes
