These are the same instructions that came with mine. Are yours different?

Instructions clearly say no spacers according to the compatibility table AND the note in step 2: "Spacers - use ONLY with
68mm mtb configuration (see chart)"
Yeah that actually is different. I can't find an online version of the instructions I got by they were from a 2010 GXP English BB box. I tossed them already, otherwise I would snap a quick pic.
