Love it - badass indeed! Surprised I don't see a dedicated trans cooler... Although the biggest problem is the probably the missing screw on the interior door panel on the drivers side! Better get that checked out!

The two coolers to left of the radiator are coolers. The small one is power steering and the big is transmission.

The transmission is also equipped with a "cooler" pan with tubes through it.

Eventually it will get an oil cooler and a trans cooler behind the cab with electric fans.

What beams are on it?
Not sure who did the work to them.

Equal length, with lots of clean reinforcement. I assume they are 7/8 king pin but I have not disassembled to verify. Still on bushings, radius arms are extended Autofab style. I assume the stuff is 75-79 or so.

Was it running when you bought it? It's a cool truck. Interesting mix of new back end and vintage front hardware. Nice open canvas, but what did you have in mind, before you laid out the cash?

It ran but there were a couple of fuel leaks. The accelerator pump and pressure regulator diaphragm were both toast from drying out to many times. $17 later the leaks were fixed.

I was looking for another bump or dentside to replace a project I had traded off to Johnny Branch. Most were way out of my price range or bone stock. This was closest to what I wanted so it fit the bill. From what it looks like someone was updating the truck and simply hadn't gotten to the front end yet.

Today I made a quick hitch for it so I can move empty trailers between locations.

Installed some new tires today... upgraded to Toyo 39" race tires. The truck drives sooo much smoother now. Going to have to convert to a full floater and put bigger breaks on it soon.

Got some beam pivots and radius arm pivots from Ryan Piggott / Dezline Fabrication in today. Now I just need to find some 1" kingpin beams (I think mine are 7/8) and some 1 ton spindles with the "bolt on" caliper mounts. Once I have that I can put together a 13" rotor brake package for the front and build some radius arms.

Started building an exhaust today... I was lucky as all of the bolts came out of the exhaust manifolds without issue. The headers that came with the truck are for a 351M (Clevelands were never offered in trucks) and were supposed to fit, the do not. The driver side fits ok but the passenger hits the starter and frame. Going to fit a later model gear reduction starter tomorrow and attempt to clearance the transmission, headers, and frame. I'll post photos tomorrow.

First, got the headers on, it was quite a chore. The manifolds came right off without a issue but it appears the engine is about 2" forward of stock. This required the crossmember on the right side to be trimmed quite a bit. Moving the engine back would require transmission crossmember modification and drive line shortening, so that idea wasn't feasible at the moment.

Second, I also installed a late model PMGR starter to create clearance and improve reliability. When the truck gets rewired I will remove the firewall mounted solenoid.

Last, I replaced the springs in the door hinges as one was worn out and the other non existent.

Tomorrow I will start running tubing back and create an X pipe or H pipe to connect the dual exhaust. Driveline, crossmember, and other items make the X pipe unlikely.

Been working my butt off trying to get this thing ready for the Fast Aid Poker Run this weekend in Parker.

Just received a ton of stuff from my friends at SDHQ Offroad just in time to get installed on this thing. Got a Lowerance Point 1 Baja antenna for my Globalmap 7300CHD, two fire extinguishers, two extinguisher mounts, Mastercraft 5 point belts, and a Pro Eagle Jack and mount.

Exhaust is almost done, been mounting a Motorola Maratrac radio, Lowrance GPS, fire extinguishers, and making sure cables and hoses are all secured away from hot and spiny things.

Right now I am waiting on some brackets my friend Ray at Rayzor Sharp CNC Plasmacuts is making for me.

Installed a new pair of Deka Intimidator batteries, Motorola Maratrac radio, Vertex 4200, and GPS wiring.

The Maratrac was having a squelch issue so I installed the Vertex as a backup. I will eventually mount it in the dash in the DIN slot. The spot behind the console is just temporary for this weekend. The battery hold downs are also temp until the machines pieces show up.

Next up is to order some sound deadening material for the interior. Leaning toward FatMat right now.

Put about 250 dirt miles on the truck this weekend at the Fast Aid poker run. No issues other than the hood pins came loose! Whoever installed them didn't use lock nuts or weld the bottom nut to the tab on the radiator support. Due to this the hood popped up while I was doing about 60MPH on a power line road... a pucker moment to say the least. Surprisingly the hood was not damaged, just the hood hinges.

I had a great time and now I have a solid list of what needs to be addressed before I use it to prerun the 500.

Little update on Gumby...

I bent the drive line due to an interference issue with a carrier bearing mount that was never removed. I dropped the drive line off at Adam's Driveshaft in Las Vegas to get it repaired and a spare made. Unfortunately it has 1310 joints so the spare will have to wait until I get the yoke changed out as I'd like to upgrade to 1350 joints with a companion flange on the rear end. I declined on upgrading at this point since I plan to use the truck in Mexico next week. Upgrades normally take longer than expected and if anything deviated from plan I'd miss my target date. Adam's is going to retube the driveline and install solid u-joints (no zerk) for me.

I also plan to replace the front beams with 1" Kingpin units and upgrade the rear to a full floater. After thinking about it, I plan to install 3/4 ton front hubs and a Corporate 14 bolt rear end from a van. The rear end will pretty much be plug and play minus putting a spool in it and 70" WMS to WMS. After the spool, disk brakes, and shaving the bottom I don't think I'll be far off a built 9" weight wise. This will also allow me to share spare wheels and tires with my Dodge.

Some sound deadening showed up today so I am going to work on quieting the inside of the cab down a bit.
