There are three kinds of 510 (1600) rear suspension arm
55502-22100 ASSY-ARM,REAR SUSPENSION LH JAPAN.(LPG+TAXI+SSS) 55502-A0700
55502-21000 ASSY-ARM,REAR SUSPENSION LH -0768
55502-U0101 ASSY-ARM,REAR SUSPENSION LH 0868- < 55502-A0800

Datsun 610 (180B) retrofits to the last 510 type.
55502-U0101 ARM RR SUSP LH 6> 55502-U0102
55502-U0102 ARM RR SUSP LH 0872- <2,6> 55502-U0101
55502-U3400 ARM RR SUSP LH 0873- <2> 55502-U0102

I knew the 180b ones do as they will fit, however they have a bit more positive camber on them.

Are you able to tell me the differences between the 3 1600 ones and the year periods for each?

610 arms have same camber as the last of the 510 arms, if you use the same fitting parts (bushings, etc).

1967 55502-21000
1968-1973 55502-U0102 510
1973-1977 55502-U3400 510 & 610

The 1967 units don't interchange with the others, I do not know the difference. They may bolt on, but Datsun says they do not interchange. Maybe the camber is different.

55502-22100 was used in LPG, TAXI and SSS (and CANADA 1300) 510s, so unlikely there were used in any Aussie models.
