Advice on how to install these disc brakes

OK @Cycleops , firstly can I say how grateful I am. It is complicated!

Just talking about the rear initially

Here is a pic of the https://ibb.co/c9fSP9 unit bolted (loosely) direct into the mounting points on the frame. The caliper is correctly positioned to grab a rotor, although I can see that some adapter might be needed to cope with the 160mm, as I assume the standard position copes with 140?

I am now looking at the boxes and they both say REAR. the website doesn't make a difference and I actually spoke to them on the phone explaining what I wanted

I mistakenly thought the pic I posted was of your ridgeback frame. The front mounts look rather different to the rears so you will very need the adapters. If you play around with the various mounts you have you should find one that is appropriate for 160 rotors.
