One More Surly Pugsley 1x11 Drivetrain Question

[tlarwa]

Last thread on this, I promise!

For those of you who have helped me so far, my sincerest thanks. For those who haven't, you still have a chance to! Seriously, I recently bought a 2012 Pugsley, and it had been converted to a 1x9, with a Deore rear derailleur, an 11-34 9-speed cassette and a SRAM X5 double crankset with 22/36 rings (but only using the 36t ring with a Paul chainkeeper - no FD). I need a lower gear, especially for the upcoming snow riding, so I was inquiring on how to best achieve this at a minimal cost. After a bunch of input, I decided to replace the 36t ring with a 32t Race Face N/W ring, and I also decided to go to 11-speed. So I ordered an SLX RD and shifter, 11 speed chain and an 11-speed 11-42 cassette. So I think I'm all set. But now I'd like to investigate replacing the crankset, getting rid of the double and going to a 1X crank. But I'm not sure what crank would be compatible so that the chainline is right. The Pug has a 100mm bb shell. The original crankset (stock) on the 2012 Pug was a double TruVativ Hussefelt.
Can someone suggest compatible 1X cranksets that will fit the bill?

I swore I wasn't going to replace the whole drivetrain, but that obviously didn't pan out I should know myself better...
