50 years and counting.
My two brothers, my mother & I, in September 1968, ordered a new 1969 R6 Scorch Red GTX, black interior, black vinyl top, buckets, console, 440-4 speed, stagger-stacked rear leaf-springs axle package with a 3.54 Sure Grip Dana 60. We took delivery 3 January 1969. I had the GTX when I sold it in the Spring 1977 so the wife & I could make a trip to Hawaii. I miss the GTX dearly. I've always had a MOPAR parked in front of my house every day since.
In 1969 I was in college working part time at a 3-stall Standard Oil gas station. The gas station owner's friend Dean owned an A4 silver 1969 RR 2-dr coupe with a Hemi automatic. The Hemi coupe had the factory black hood stripes and American Racing Torq Thrust wheels. A beautiful car with which I still have day-dreams.
Late one early-Spring 1969 afternoon, while I was on duty, Dean brought the coupe in and we put it on the lift. Dean had a box of headers and two Coast-to-Coast glass-pack flow-through mufflers. Dean asked for some used motor oil which he poured inside each glass pack. Dean set the treated mufflers outside next to the building and lit them on fire. Dean called this the break-in period!
The headers were installed in short order and the blackened mufflers were slid into place. It was after closing time by then so Dean, his buddy who helped and I went for a test spin. It was impressive feeling the Hemi work past 60 mph in the dark at full-throttle.
Dean later spun a rod bearing at 8,500 miles while the Hemi was still under the 12 month/12,000 mile warranty. Dean got concerned and traded the broken Road Runner in while the Hemi still had some warranty left. I am sure Dean truly regrets losing the car.
