Incidentally, the M-car guide pins are a very good thing to have around if you run Tomy Turbos or Tomy SRTs. The front axle holes on those chassis can get loose and because they pop in from the top they can get dislodged while running the car or in a wreck. The M-car guide pin fixes this problem very nicely. I use them on my SRT race cars. If you're going to order some, consider getting some spares.
