Took the rear cover off the other day and seen the edges of the top and bottom spider gears are broken off everything else looks fine been doing some reading seems a little intimidating but I'm gonna try it. Should I use original bolts or is it ok to use the new ones in the set and are the torque settings the same from what I've read as long as I put everything back in the way it originally came out it won't be out of line is this right any info would be helpful
