4 shocks I removed from my '66 fastback six years ago. Front shocks are stamped FIRM, NORMAL, SOFT / FOMOCO ( script in oval ) / 3829692 / FRONT / letter "G" / MADE IN USA / P6CD. I have been told by a noted MCA judge these are original for a '66 Shelby. One stud needs replaced. Rear shocks are stamped AUTOLITE / MADE IN USA / C4ZF-18080-C / P6CC / REAR. Unsure of value so will accept offers. Would prefer to sell all four shocks as a group. E-mail for more info or photos.
