Thanks Phil and Bob.
The yoke on the gear box is in good condition and I have a nos seal ordered.
The diff yoke/input is badly groved from the seal steel spring wearing against the surface, I am looking for a replacement.
Only used speedy sleeves once before but I can turn the yoke down in the lathe to the size needed to fit a modern seal. Statewide Bearings here in Perth are a great help, you take in your old bearing or seal, (they don't ask "What's it off?) they measure width, id and od and supply you with one that fits.
Even bought new shackle bushes from them, Teflon coated...
