here is some information on the 300 Hurst cars
300 Hurst (1970) In 1970, a limited production, special edition 300 would be produced. This car was assembled by Chrysler and refined by the Hurst company with special striping and two tone paint treatment, deck lid spoiler, wheels, and the like to approximate the panache of the 300 letter car. The high performance 300-Hurst was a Chrysler 300 modified by Hurst Performance Corporation. Built in Detroit by Chrysler as a Spinnaker White coupe and shipped to Warminster, PA, where it was modified by the Hurst Corporation in their plant. It was offered with saddle color leather bucket seats that was an Imperial interior brought over from the Imperial plant and installed on the Chrysler factory line. There were fiberglass power bulge hood (with functional air scoop); dual, depressed, rotary hood latches and fiberglass deck with rear end caps. The car was built with a factory hood and Hurst took the metal skin off and installed a fiberglass skin. Factory deck lid was removed and an all fiberglass one installed along with the spoiler extensions. Some had spoiler supports installed at dealers later as they were starting to crack from people using them to close the lid. There was special paint (Spinnaker White) and Satin Tan color accents with special striping and an integrated wing type rear spoiler. This Tan was in reality a Cadillac color, done at the Hurst plant. Stripe colors were actually Chocolate and Orange. Often thought to be black. The Chrysler 300 Club International, Inc. had them reproduced. The Stripe kit is still available from vendors. Other standard features included: 440-TNT engine; TorqueFlite automatic transmission; heavy duty suspension with sway bar; styled road wheels with a matching stripe circle around the center and raised white letter tires. This was Chrysler’s last attempt to make the 300 something special and the 300-Hurst is considered in the same Class as the Chrysler Letter Car Series. Note: Limited production was due to Chrysler and Hurst taking so long to decide and then each thought the other would advertise it. The cars just showed up on the transporters without a dealer order.
