[Fot] TR3/4/5/6 Syncro Cups

[jeff_durant at comcast.net]

I'm rebuilding a CR gearbox for my TR6 using a Kastner gearset and realized I used my last factory syncro cups on another CR gearbox build.  Who offers the best (closest to factory) syncro cups for the big TR's these days? I've tried Moss cups I'm my brother's TR4A trans rebuild and they were marginal.  Anyone tried the TRF or Rimmer's premium ones?
Thanks,
Jeff D.
