I've found two different part numbers for the Atomic main spring. 21-0574-00 and 21-0570-00. Anybody know if there's a difference between the two?

Yep, the 21-0570-00 also comes up on the T2X schematic. I don't have a T3 schematic, but I'm betting it's on it too? Basically the "newer" model regs as far as I can tell changed to the 21-0570-00, but have found 0 info on if there was any function change or for what reason there was a change.@Wookie will have the definitive answer. :-D
In the meantime, looking at a couple of schematics I see the:
21-0570-00 listed in the ST1 schematic.
The 21-0574-00 is listed on the T2, T1, T1X, B2, Z2, Z1, M1 schematic.

Well that confirms that the spring part number changed starting with t2x and continued. Still wonder if it was only a number change or if something about the spring that changed.At home, too sick to do homework-see attachments.
There was a rare failure incidence. The metal was changed and all new springs are etched with an alphanumeric on one end.
It was recommended at a seminar a few years ago that springs below Nxx (where xx is a number) should be replaced. No recall, just an advisory.
