Quick update. The block came and I was quickly able to ID what arms I needed. Turns out they were these ones, as I suspected.
They were £11, so the block has cost me £36 total and should now fit almost anything big. I can order AM4 arms too, so will remember that if I ever change it in the future. The block weighs a ton. It's machined from a solid lump of brass with a copper cold plate. Heaviest block I've ever had.
Due to the "Must spend £20 thing" on Aquatuning I got two of these too on sale for £4.38 or so each.
I am currently running odd ones as the original fittings leaked. So I will swap those out whilst I am there.
