Set of rear callipers which don't look that old I'm not sure if they are 4x4 or 2wd
But if someone knows how to tell the difference between 4x4 and 2wd there input would be appreciated as I've got a further 4 pairs and I'm not 100% sure

Hi Mick,
I think you have 2wd calipers in the picture (both are near side or passenger side)
The standard 2wd ran solid rear disc whereas the 4x4 ran vented discs.
If you measure the gap where the disc slides into on the caliper carrier this will confirm it.
2wd ran 10.5mm thick rear disc and the 4x4 ran 24mm thick rear discs.


On the left standard sierra and on the right 4x4 sierra cosworth

If you have a 2wd/standard sierra pair in good condition, seals intact and sliders freely moving I might be tempted for a pair.

 

Wasn't 4x4 a 20 - 21mm disk?

 

Sorry yes they were 20mm thick, the fronts were 24mm thick.
