Car Feature: Jet-X, The 1972 Plymouth GTX that Mopar Never BuiltBy Brian Lohnes Posted 07/10/09

Here's a car from the cover of the October 2009 Mopar Action magazine, and one that's being debuted at Chryslers at Carlisle, July 10-12, just as this is being posted at BangShift.com. It's Gary and Pam Beineke's brand new creation, Jet-X. This is the 1972 Plymouth GTX that Chrysler never built, it has 440 Six Pack power, and if you are a serious Mopar fan, you'll really respect both the story and execution behind this car.

It was not a banner year for Chrysler muscle cars in 1972. The Hemi option was dropped, and the air had been let out of the muscle car balloon with government air quality regulations and an ever more skittish insurance agencies. It was also the first year that the Plymouth GTX went from being an actual model to becoming an option package. The luxury/muscle machine was now demeaned into being a dress up option. That wasn't always the plan though, as a real 1972 GTX had been in the design works as early as 1968.

Before the age of computer aided design and modeling, all the physical design elements of cars were formed by hand and actually mocked up in a design studio. Clay sculptors and other artisans aided in the process with the designers, and fullsize clay models of proposed cars were created. Such was the case with the 1972 Plymouth GTX that was in the works in 1968. A few years ago, noted Mopar collector Steve Juliano found the original Chrysler studio photos for the 1972 GTX as designed by John Herlitz. Working from just those photos and a couple of interviews with Herlitz (who is now deceased), Gary and Pam Beineke brought the car to life.

The build took the pair a year to complete in their home shop. Remember this is not Gary and Pam's business, but a hobby they take very seriously and devote a lot of time and effort to.
