You say that one of your cars was a "sept '69" one. Is this when it was first registered, when it was built, or does it have some sort of compliance plate with that date on it?
A car that was actually "built" in Sept '69 would be a "'70 model", regardless of when it was registered.

If you back up [down?] the thread, you will see where i have writen a whole stack of serial numbers & you may be able to pick the model from that. If not, then see if you can post, or PM me the serial number & i will tell you what my parts book says.

With the popularity of these early Datsuns, i am beginning to think i was 20 years ahead of the game. Most people laughed at mine,... till i drove by them,... towing a boat,... uphill, then they just thought i was eccentric.
