there are factory anchorage points in the C pillar. must be due to ADR's (Australian Design Rules). Did the US 1200's not have lap sash rear belts?

I don't think any Aussie 1200's had cloth seat trim.

US 1200s did not have rear 3-pt belts, just lap belts. I wonder if the mounting points are there ...

did they ever have head rest

Good question. The front seats (by shape) are not original compared to any I've seen. Did other Aussie sedans have seats like this?

Front seat headrests were optional. You could add them later to the original seats (all 1200 seats had the holes for the headrest).

They look like the later Sunny ones, I had the same cloth trim in a 1.5 ZX .

I actually have a 1200 with REAR seat headrests! That's right, I said REAR seat headrests. I don't knoe if they are something the previous owner had installed, but they are the only ones I have ever seen.
Speaking of the previous owner, he made a remote trunk release by attaching a piece of coat hanger to a starter solenoid! This was hose clamped in behind the plastic interior parts and used to pull the mechanism. It took me a while staring at it to finger it out when I discovered it.

OK, dimlight65 ... now we are dying to see a picture of the rear-seat headrests. Or better yet, the remote trunk opener.

well the boot opener ive seen for sale in last years jaycar catalog witch i have a copy of im sure it was in there you just install it and then hook up the wire through a switch and its set it also needs a spring to open the boot if you want it to open up automaticaly unless you have to lift it urself
