Hi again Bob & Phil
Thanks for your further comments and advice. So far I've obtained the two inner seals, NOS $AUD20 each and the outer bearings, NOS $AUD10 each. And through a quick trade with my good mate Max I obtained the two outer seals, again NOS. I'll re-assess the inner bearings and probably use them if I'm happy with them. Now I can re-assemble the rear axles.
Bob
