Thanks for the intel. I’ll check M&M. about the rig the third listing, the grey one, it’s interesting to hear you don’t like the suspension geometry. I think it’s an old Proffitt build.I suspect its due to folks not having an emotional attachment to a rig that they didn't build. Much easier to part with. I'd add that in my opinion, the builder who originally built that rig doesn't have suspension geometry figured out for proper link suspension builds. One of my 40's has their rear link kit, and it has so much roll steer, it is dangerous to drive at speed. Getting the geometry right on a linked suspension is so critical to both safety and comfort. My tube chassis buggy also has pretty poor suspension geometry for anything but crawling.....I got to drive a buddies Jimmys 4x4 buggy and I was absolutely blown away how stable and smooth it was. No roll steer or weird body roll over little bumps, where as mine is all over the place.
Get in touch with M&M offroad in North Carolina and ask PJ if he knows of anybody selling one of his buggies. They have built some very bad ass 40 based buggies.

Its just leafs in the front. There are hydraulic cylinders at each corner to “force” articulation, that's why you see it doing the "peeing dog" pose in one of the photos. I expect the ride is very rough with those hydraulic cylinder's, but it was purpose built as a cone dodging crawler.
This blue one is/was owned by Don Robbins, there are some mentions of the 40 on various forums from the early 2000's. There was a nearly identical one (FJ40 based, front spring under, 4 corner hydraulic cylinders) built/owned by Tracy Jordan. I believe both of these rigs were modified or built by Twisted Customs in South Dakota.
Interesting video of the blue one:
Sure, it is unique, purpose built and not for everyone, but it was pushing the boundaries in the early day's of rock crawling and hopefully someone saves it from rotting away in a field. I bet it is still a capable rig, and definitely has a "wow" factor that would bring attention on any trail it was on.
I bet @wngrog may even have some photos of it or Tracy's 40 in action from his days as a rock crawling competition photographer.
