I looked in to buying the kit and rebuilding mine at home. And then, when I compared the price of sending them off and having PWC Muscle do the job or doing it myself, there wasn't really that much difference. Plus, I got the knowledge that PWC has done hundreds of them with very satisfied customers.... instead of me, having NEVER done the job before and not having any of the special tools to do the job.......well, you get the picture........
