The Willys pic is awesome! Did it suffer a fate similar to the Cheyenne?
The Willy's was amazing. Raced 20-30 weekends a year for 8 consecutive years. Few of the tracks didn't include at least a small amount of air time. Never blew a motor and never lost a tranny/tc/axle. On several occasions in the early days a hard landing would ram the front driveshaft against the bell housing and break the shaft. After about 5 of these dad replaced it with a solid stainless steel shaft and, even though you would think the bell housing would be the next to die, that fixed it.
The end fate of the Willys is most sad. I had it up until 2 years ago when some crack heads broke into my metal shop, took it, and crushed it for scrap $$.
