Replacement springs for Suntour SP NCX seat posts?

Hi, Ebikers! Really excited to soon be receiving our M2S fat bikes. I'm certain that I'll be putting on suspensions seat posts, and the Suntour look to do the job, but I can't seem to find a link/source for the replacement springs. My wife will certainly need the light one, seeing as she clocks in around 100lbs wearing a heavy sweater. I'm 180 +/-, so the medium spring might work. We'll see. Either way, I need to be able to order a different spring. Anyone got a source? I can find the posts easily on Amazon and other places.

Thanks so much!
