Quick question on GXP mountain BB spacers
 

I'm switching my two year old Firex crankset off of a frame that has a 73mm bb shell to another frame with a 68mm shell. I can't find the two original spacers that came with it. I would assume that they are 2.5mm a piece, so I was going to break out the micrometer and find something to replace them. Can anyone verify the width of those spacers?

yeah, it's 2.5mm
