I just got my prop shaft out, it actually came out very easy. The u-joints I was sent are all balls and have the retaining clips on the inside and the ones from the factory are on the outside, I emailed the company before the sent them with all the bikes info and said these are ones I need, just wondering if they will work with the clips on the inside, the part number is A03-E6338 Universal joint 24MM. Bike is a 2011 850xp EPS
