V3.1 cut length discrepancy? 140mm or 160mm?

I’m about to order my 2020 extrusion and I want it precut… do I cut at 140 or 160? I see a discrepancy.
there are measurement discrepancies between the BOM and the build https://ohai.satnogs.org/project/satnogs-rotator-v3-mechanical-assembly/hardware/
one states the 2020 measurements as 160mm and 102mm the BOM(rotator-bom.ods · master · librespacefoundation / SatNOGS / satnogs-rotator · GitLab) included in 3.1 states 140mm and 100mm…
which is the ideal cut length?

Different lengths are different versions of rotator:

• The 140mm and 100mm are referred to v3.1
• The 160mm and 102mm are referred to v3.0.1

The ohai assembly guide, is referred to v3.0.1. In the wiki - Build Sequence, the assembly guide is referred to v3.1, which is the latest version. Also here you can find a report about the current status of GS hardware.
