good thread here mate used it for my rear disc conversion and it helped alot in sourceing the parts the only thing that you dont mention is that the rear disc reduces the lengh of the wheel bolt going into the wheel because the old drum is about 5mm thick but the rear disc is about half an inch thick so your reduceing the amount that the bolt goes in to the thread. thought i might mention this as after all they do hold your wheel on. i know that the bolt feels tight when its in but its not in the thread enough.
