The ones I bought from Macs a year or so ago had the taper wrong. They sat down in the hole like an original, but you could wobble it a little. In checking with a caliper, the taper at the big end was a few thousands too small and at the small end, it was a few thousands too big. I can't remember the exact numbers, but I've got a pile of them sitting on the desk in the garage.
