The "intriguing" wheels on that Challenger were the first attempt at an aluminum Rallye wheel. The person that designed them had no concept of scale, using original-size holes in a much-larger-diameter wheel, making for one ugly chunk of rolling stock. People stayed away in droves, and a newer design has since become available that's much closer in overall scale to the original. My friend put a set on his '71 Charger R/T. They're still not as pretty as the originals due to the rubber-band tire sizes required, but they're definitely better than what that poor fella's saddled with.
The A4 Challenger is a bit of an odd duck, being a 340 but not a Rallye... and the '79 Ramcharger's got a decidedly 1978 front clip on it.
Though the confirmed word seems to be that the J-series Jeep pickups went out of production in 1988, the Jeep dealer for whom I was a parts manager in 1995 had a 360-4V J20 tow/service truck. It was dark blue with a tan interior and had a light-duty hook setup in the back; it was not a dually. Both the registration and proof of insurance said the truck was a 1991 (yes, I got pulled over in it). I have no idea how they got it or any story behind it, and my poorly-worded inquiry to one ot the owners got me only a confident,"Yep" as a response and I didn't press any further. The dealer had been in the business of selling brands that would become AMC as far back as the mid-1930s, so maybe they had some connections that could get such a vehicle built. I honestly don't know.
