I sourced the parts from Tyga-link from here-,used the workshop section to educate myself,plus any requests for assistance were answered here(thanks all).doing the job didn't take that long at all,just have the correct tools and dive in is my advice,I would never have attempted a rebuild before,but I now feel more than confident to recommend that you give it a go. I posted my progress here ,do a search,it may be of assistance.
