I was told about this site from a fellow member so I thought I'd post it here. I got this throttle kit, its a bit pricey but it has a large variety of various cable ends, clips, cable stops, etc that are typically hard to find as separate units. Very good quality too. Depending on how long your buggy is there is almost enough here for 2 cable kits.
