I think he means the upper requirements for crafting post junkyard surprise nerf, I don't have the numbers in front of me but I can tell you that the workbench gives you a 15% boost to your skills, you need to look at the threshold and work backwards (that's what I did). I think for mechanics, electronics and tailoring you need an effective skill of 128 but I'm not certain, I found transferring two points from one stat to intelligence works in lieu of junkyard surprise (albeit at a cost to combat efficiency)
