Let me start off by saying that this thing has always been a pile and the body really isn't worth the time it would take to save it so I have no remorse as far as cutting it up.
This thing was my first vehicle, my dad bought it for me in my sophomore year of HS as a father/son project (along with his 66 GTO) and funded the rebuild of the drivetrain and other things needed to get it roadworthy (I use that term very loosely). It is an original v6 model with a t14 trans and a dana 18 t-case. It was completely and totally rotted out when we got it, there was no floor, just a stop sign someone hacked up to cover the hole where the floor should've been and that was just the start of it. Regardless, the first time we started the motor is was knocking to high hell, so it got pulled and sent off to get rebuilt. The entire thing ended up getting rewired, trans got rebuilt and the top cap put together backwards by novak adapters so it shifts backwards.......and a ton of other stuff, suffice it to say, more money was spent on parts than the thing was worth which I shouldn't be surprised with.
I drove the thing for a couple years until I got my C10, and them it was just my backup vehicle when the C10 decided it didn't want to start for whatever reason or when I wanted to go wheeling and my friends needed a recovery vehicle, but this thing always worked, it ran for years with little to no changes until the cheap chinese ignition coil exploded and ended up getting replaced with the original one from a 66 GTO.

Also yeah, the RZR seats weren't my first decision but good seats are pricey and this thing never warranted them. raw deal flex 2.jpgposted up in a rivebed.jpgtable_mesa_2.jpg
The one gripe I always had with this thing was the suspension sucked, it was really bad, worse than it should've been, so in my head, I'm thinking why would I go buy new leaf springs and whatnot to rebuild it to stock when I can cut it up and turn it into a mini 4800 car. So that's what I did. I started to disassemble it and cut the rear of the body in a way that would allow me to push the wheelbase out in both directions (also taking most of the passenger quarter panel rust with it) and also run much larger tires. recent teardown.jpgfirst cuts 3.jpgfirst cuts 2.jpgframe no body 2.jpgJeep seperated.jpgFrame Plates jeep.JPG
I have one big issue with the way I have seen most of these CJ5s built and that is that they look like monster trucks, and for me that isn't going to fly, so while I will be retaining most of the stock frame (which wasn't the original plan) it will be getting plated and boxed, and the rear foot of the frame and possibly a chunk of the front will be going so I don't have to sacrifice too much up travel while still retaining a lower ride height, if worst comes to worst, I suppose I can just body drop it, but ultimately this will be a go fast type rig, not as much of a rock crawler, so having a lower ride height isn't the end of the world as long as it rides and handles correctly.48in SC Trailing Arm.JPG
I still have a lot of deliberation and design work to do as the build comes along but hopefully it will pick up pace after my c10 gets done, ultimately my goal is to have this done by KOH 2025.
 
Sticking with leafs or linking?
It will be getting 4 link front and rear, for what I'm doing with it, it makes more sense to do coil overs than trying to figure out custom leaf packs and mounting. Plus I already know a whole lot more about designing suspension geometry with links as opposed to leaf springs.
 
Wrapped up design on the rear truss for the Dana 60, I'm not worried about running a full width truss at the moment mainly because this thing is going to be around the 3k lb. mark and there are probably other things to be concerned with beside the housing getting bent.

Following. This is a rad build. Dont see anything but full buggies in 4800. Rooting you on!!
It more than likely will never get raced unfortunately, but its getting built to class rules regardless in case it does, but it will absolutely see pre-running duty and serve as a trainer if I ever do get into racing. Thanks for following the build though!
 
Wrapped up with plating the frame, now I just need to generate the cut files for the inner box plates to weld those in, and wrap up with cleaning the stock bracketry off the frame since it won't be used anymore.

Haven't posted an update in awhile on this thing, I got the stock axles out, started to get the frame boxed, which is almost done save the small portions where I cut out the rear-most crossmember that I initially planned to save. I also got every single hole filled, all the brackets off, powertrain pulled and started designing the rear suspension, I also lopped off the front section of frame to the crossmember that holds the grill. Most of it isn't shown in these pics mainly because I just don't have good pictures of all the work.

Can't wait to see more of this thing. Looks great so far!
Yeah, I need to get moving on it, I've been throwing all my time and money at my C10 and miscellaneous business stuff trying to get that to start producing income, but I plan on getting a good pile of tubing together in the next week or so to get going on the cage work.
 
I decided to go ahead and put the tub back on the frame since I've more or less finished welding on the frame plates. I did decide on changing the route I'm going, I will probably end up lopping off the entire rear of the frame and doing a more traditional back-half than what I had planned, just so I don't completely kick myself in the face later down the road for leaving the notoriously weak stock frame in place, I know I will kick myself for leaving the front half and not just starting from scratch though. I also went ahead and put the powertrain back in so I can build around it and to make sure there's space for the small block I have planned if the v6 bites the dust. Then I put the grill and hood back on just to keep the engine out of the elements, and again, to build around them.
I've run into a couple of issues, mainly the seating and cage location since this thing is so small the B-pillar was initially going to come up right where your shoulders would be, unless I stuffed the seats towards the dash which isn't a solution I even considered. I've already come up with the solution to the problem, just waiting on material in order to start cranking out the work.

I went back to square one, and started to lay out some tubes on the chassis, I was having trouble trying to figure out how to mount to the rockers (or whats left of them) since I cut off about 1.5 inches due to rust, this is what I came up with, the upper tube will be where the main hoop for the cage ties in, obviously it will be completely triangulated in to the frame, so that little boxed triangle piece section doesn't end up being the weak point (I know it overhangs the frame a bit, it will get trimmed, I guesstimated the frame width and lost). The tube going parallel to the body will get shoved over as close as possible before welding it so I can minimize the shear load on that rocker/outrigger joint.
I still have a long way to go but this is probably the hardest part of building off this body due to the space constraints and how little body I have to work with because of the rust. On the upside, cutting the rockers out ended up giving me a sort of boat-side effect as if I needed it with how small the body is.

I also think I've come up with a fitting name for this thing given its a very barebones, function over form type of build, I've always tossed around RJ (Rusty Jeep), but from here forward I'm going to be calling it Skeleton Crew, given that minus the safety devices and shocks/suspension I'm really using the bare minimum to get this thing going and keep it simple so it isn't maintenance heavy, just hop in and go, kind of like its always been for me.
