No- the MC must be the ATE unit; it's distinguished by an entirely

I do not buy used car parts off ebay.  I don't buy used car parts 
period, actually.  I don't buy anything off Ebay, either- it's the 
largest source of fraud complaints in the US, and now you know why.

   I would never buy brake system components except new; I don't even 
buy reman'd brake parts.  MC's are pretty much "consumables" and are 
also impossible to inspect/judge the condition of, even if you're 
holding one in your hand.
