He had a magnetic surface plate and he ground the spacer from .034" to .026" Slick!
Maybe the next guy who needs a different spacer for his aftermarket axles will find it at MB but the thinnest one they had access to was 1MM or .039+" which was way too thick for me
And a word of warning about AM axles. You get what you pay for.
Not only did I have the spacer issue but the new axle end bolts were too long and I had to reuse my originals!
