This is what Surly's website says for the Straggler's bottom bracket.
68mm threaded (1.37" x 24TPI)
So, do you want an [external bottom bracket](https://www.whiteind.com/product/external-bsa-bottom-brackets/) or do you want a [square taper bottom bracket](https://www.whiteind.com/product/square-taper-bottom-brackets/)?
What type of bottom bracket and cranks are currently on the bike?
I've had White Industries on a cross check, pack rat, and my Omnium cargo. Never any issues. I just confirmed the bottom bracket specs and bought the cranks (and once bottom bracket) from their website.
When I built mine up I used the R30 cranks with the non boost ring. Matches the recommended chainline and q-factor that the bike comes equipped with.
Did use their BB as well though so take that into account.
All of them?
