do u want one that is good enough for the track or a real one?????

cuz if u just want one good enough for the track just get one of the plastic lines (looks like a phone line all coiled up and what not) that has a key ring on one end and a clip on the other (clip that u can attach to yer belt or somethin) drill a small hole through yer kill switch slider (in one side of that peak part and out the other side of it) then just spin the keyring through it! thats all ive ever used at the track
