Abstract
A convertible top stack linkage is provided that is formed, in part, in a thixotropic magnesium molding process. Many structural parts of the convertible top stack linkage may be thixotropically molded. A pivot link of the top stack linkage is pivotally connected to two bows, for example, the three and four bows of the top stack. A five bow extends between and is attached to right and left pivot links by right and left pressure links, respectively. A pivot link is provided that has a triple pivot connection to a tensioning link, a center rail and a rear rail. A main spring is secured to a pivot pin and connected to a main pivot bracket on the vehicle to provide a counterbalancing force on the balance link that assists in lifting the top stack linkage as the convertible top is retracted and extended.
