Princess calipers on Granada mk2 uprights

[simonjrwinter]

I'm using Mk 2 Granada uprights on the car I'm building. I've been told that princess calipers (with spacer kit) are a useful upgrade. Has anybody done this? is there anything I should be aware of or are they a bolt on upgrade?
Thanks
Simon

Think Princess Calipers are rarer than something very rare indeed.

I was certainly able to fit them onto my Cortina (IV/V) uprights together with Capri vented discs. the only thing I had to do was to remove the backplate
