Oh, and thanks to stovebolter ave Razey I now have another gear shifting box to play with. I'm gonna clean that sucker up and see if it will be any tighter than the one I've had in there for the last 7 years.
The existing one leaks grease out of the back end like a sonofa... and it seems like there's a tad too much of a gap between the shifting gates.
Thanks Dave!!!
