I think they cost me all of about $20 each. They're cheap Chinese-made mics, but they work ok.
Well, .002 would be almost exactly the difference between my old stock gearset and a theoretical spec of "0.3700". I'm glad to know that this was by design- it worried me slightly.
It also bothers the hell out of me that the Mazda catalog is looking increasingly wrong in this regard. I really wish they'd give the complete VIN suffix, and not just the last four digits.
Holy hell, I'm retarded. Literally, as in "My mother smoked meth during the second trimester."
Those numbers AREN'T VIN suffixes, they're datecodes! How the hell did I never realize this before?!
9301 means "year 1999
, month 3
, day 01
It is there, in small, smudged print at the bottom of the catalog page. As ***** Wonka said, it's right here, in black and white, clear as crystal:
136036 definitely puts my engine in the "middle" production class, between 9301 and 0701.
Hmmm. So going back to the '99-'00 catalog:

So what the hell is up with Rosenthal's website?
