What rear brake caliper/carrier set-up for disc conversion?

Hi all,

Any ideas on what caliper/carrier (brake set-up) to use on a rear disc conversion?

Here is a pic….
 

Or if anyone could tell me what these calipers are from as I got them with the car but missing a drivers side rear carrier and struggling to source one without knowing exactly what these calipers are. So if I have an idea what they are I can just get another caliper carrier for the other side.



Im up for both options!

Thanks!

The caliper looks like the mk3 item with the internal spring.

yarp mk3 caliper, carriers mk2 or mk3 they're the same anyway
