The > do fail in the closed position. My impression was that the ones he was talking about were all the old original bellows style. Brazilian Bi-metal spring? Are you thinking of the current Mexican ones which appear to have a spring there, or is there a third style that I've never heard of? I've never actually seen any of the Mexican ones, but my impression was that they used the traditional wax pellet concept, like those used in water cooled cars. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
