Have refilled the gearbox with 4.5L of sae80 api G4 oil, and fitted a new gear change nylon bush mount. The earth strap though still there will just clean as i have routed a larger one from the starter to the motor mount.
I would suggest to anyone removing their gearbox, if there is corrosion in and around gearbox/chassis mount, airblow the bolts holes, i was surprised how much crap came out. Because of this i decided to fill all bolt holes with metal filler (glue,paste whatever you want to call it) and redrill holes, i now have some piece of mind it is strengthened.
Will update some when I get the new bearing............ darn and the fishing season has started!
Couple of pics added
