Either kit is fine if you understand what the lever on the transmission end needs from the throttle.

Sometimes they bolt on and nothing else is required but quite often the geometry needs to be adjusted. I'm not taking about the position adjustment, which is all a factory set up would need because the ratios are all correct from each pivot point.

The aftermarket kits will require fine tuning the ratio. If you do not know the difference between ratio and the linear adjustment. Find a factory set up.
