Firstly I would like to thank all the people for the emails re my motor troubles
I have been successful in locating oil pump parts for my motor, thanks Chris Elm, and Obsolete Autos
If your chasing these pump parts I suggest you keep an eye open as they are still around. Auto Surplus in Melb are having the gears remade and they will be available in approx 2 weeks. Note they are not making the shaft so you will have to use your existing shaft from oil pump, also they have new relief pistons and springs. I was able to get the piston and spring off them to complete a full kit
Cheers ChrisB
