Cool. Well, I now have 3 sets of cranks for the Surly and a couple of BB and chainring options. :)
It says it wants BB-MT801 but is the 501 the same thing just cheaper or do I need a different BB too.
EDIT: Just looked and I did buy a 73mm MTB BB for the GRX cranks. Maybe I bought them at different times and just wasn't thinking straight at the crank purchase time.
I presume there's a way I can work out what my chainring size limit will be? ie. approx how wide will the chainring sit + diameter of 38T ring or whatever?
I thought the 12s stuff was all for Boost and so too wide?
Also saw Alugear rings but ordered a much cheaper "Deckas Narrow Wide Chainring Round 38t 96bcd Asymmetrical Black" because I wasn't sure what cranks I'd end up with and the point of this was new cranks was supposed to be cheaper than just putting a larger ring on the Middleburns.
Someone posted these in my Wanted thread:

Would they work if I threw on a larger chainring? My brain is melting.

Ok, spec mentions 135mm OLD and 73mm BB so do we have a winner?
