Gear Input Driveshaft for 410

[Lowie]

Dear folks,

when searching through the net, I found two parts, with a different part-number .. for the same job:

TDR310027 Team Durango Gear Input Driveshaft
and
TDR310116 Team Durango Driveshaft Gear Input (2.0mm)

What's the better of those two? My guess, because of the larger partnumber: 310116 will be an update-part .. but I'm not sure of that.
Any insight?
thx!
