Well my hope to push the rebuild off to the end of the year didn't work out. Started noticing the box had more whine to it. I had been gathering parts to rebuild a spare box a friend was going to lone me. That box unfortunately has a stuck flywheel. Either way mine is now in pieces, my double roller fell apart, luckily it looks like it was just the plastic pieces that disintegrated.
I have a bunch of pictures on my blog. Not sure if I'm allowed to post the link here but if it does work then perhaps someone can take a look at the pics of the gears and let me know if they see anything I should be replacing. I already know I need a new input gear (I messed it up) and the 1st/2nd gear selector has a bit of play so I'll be replacing that as well. Just not sure if the other gears are good, I honestly don't know what I'm looking for in terms of wear etc.
Either way heres a link to the post.
