Recoil starter

Does anyone know if there is a difference in the 08U78-HP5-100 Recoil starter kit and the 08U78-HP7-100 Recoil starter kit. I purchased one online, advertised and in a HP7 box but the instructions indicate it is a HP5 kit. Looking over the two kit’s instructions it does not appear that there is any difference in the parts, just some additional steps to install it on the newer model ATV. If anyone has any inside information concerning the above mentioned recoil starter kits, I would greatly appreciate your insight.
