Need clarification on lower ball joint

[Ped]

So I picked up this lower ball joint on Ebay the other day as it was too cheap to pass up (impulse buy). Not that I need one, but 'just in case'. Having looked at it now it has arrived, it does not look correct. It was listed as for a 'Nissan 280zx'. Below is a screen grab of part numbers that they listed with it, but I don't know if these are correct either? Seems to be for a Nissan Pickup?

Question: is this for any of the Zed models?

Here are some pics (it is stamped 'R' for right)...

doesn't look like an S30.

Thanks, I will do a bit more digging and see what I can find. Looks like it may also fit Cedric and Gloria from the 1970s.
