[Motiv8]

Otto, It's my understanding that a while back asbestos was eliminated by law in gkt mfg. Stock on hand could be used until depleted. Molina had a good stock and hopefully can accommodate you. Other mfgs have gone to these various modern methods which are very good. Nitrous, Harleys, etc, they're great. the old asb/ coper clad probably best for you. Forget the solid copper and O ring thing for you. I deal w/ solid copper gkts on British bikes and other special applications. They can be annealed, if desired.
