Thermostat housing part number help plz...

[Slideshow bob]

Hi all, I'm trying to track down the part number for a thermostat housing for my JDM '76 FairladyZ. I know it was also used in a 280Z of the same era.
I have part numbers for the 240/260Z but they are not compatible with the fuel injected cars.
Any help would be appreciated cheers.

I would have thought that the 280ZX one should be the same.

For '75-up L20AE, two part numbers:

11061-N4200 HOUSING-THERMOSTAT
superseded by:
11061-P6521 HOUSING-THERMOSTAT

I don't see any date for the supersession or fitment caveats, so both will probably fit and work, but the P6521 version is the most likely to be available new.

That's great thanks for the information, fingers crossed I can order one from somewhere.

I may have a used one in my stash. If you’re interested, give me a few days to find it:

Thanks, Definitely interested, look forward to hearing from you.

If Huw can't find one for you I might have a new one but not sure if it's a 260Z or early 280Z one, I can't check until the end of the week.

Appreciate it thanks

Found it. A bit scruffy but in good condition they should clean up nice. No corrosion in the lower casting with all the threads looking in good condition. Just a bit of corrosion in the top cover casting around the lip of the outlet pipe.

Drop me a pm if interested
