need at least 1 lower ball joint , and maybe 1 or 2 upper ball joints.
 
I'm guessing they dont make them any more , so , what can i use that fits , or am i restricted to only ball joints that are labled B10 or datsun 1000 (not sure what a cherry or sunny of those years run) year of manufacture 1969-1970

let me know if you have any luck

oh i just remembered my nephew's wife works for nippon Denso (car parts company based in japan)
here in Australia, so i reckon she " should " be able to maybe .. perhaps.. source some bits, ill have a chat tonight and see whats what. I'm fairly sure Denso is toyota parts based.
 
well that didnt work out , their stuff is for newer cars.
 
I did find the  http://www.essnsa.com  site , but cant e-mail them some unresolved issue .. so i may try and fax them tomorrow, they seem to have all the bits im after

Since Datsuns share so many other parts, it might very well be possible to find a close match. Problem is there is not much room to move in regards to drilling the arm out to fit another pattern, since it is a tight squeeze on the arm with the radius rods and the spring rest.
