What Olive and inset for SLX brakes

I bought some of the Slx brakes (M675) from the Ribble PSA.
Does anyone know what olive and insert is required for shortening the cables?
The cables are marked BH90 – is that all I need to know, does it matter that they are SLX levers?
I’ve found universal inserts and bh90 ones and I assume it’s the bh90 that I need? Just checking.
Thanks.

You need the shimano bh90 ones. I got the for £5 from crc yesterday.

Excellent, cheers for that.

Was there not a spare insert and olive with them?

The olives are all the same as the external diameters of all Shimano hoses are the same. The insert is silver on Bh90 hoses and gold for all other hoses. You need silver for your brakes.
