I did the mandatory search and found nothing on this.

I'd like to get my in/out pad contact adjuster working on my ultimate. The worm gear is stripped and I assume so is the one it contacts. So has anyone worked on these, is it easy/hard, special tools, not worth the effort. Do I order all the internal parts or will some of the ones I have be re-usable. Are parts interchangable between sevens and ultimate...it seems like they're not. Are there any pics or how-to out there?
