Story: This truck has quite the story. It was given to the current owner by his grandpa, hence the project name, then was parted out by and nearly lost after the first shop it was being built at dissolved. When it came to us, it was nothing more than a rusty cab and doors that had been blasted and left. The floor, rockers and part of the firewall were all rotted through. The box was beyond saving too. It was the perfect candidate for something wild.
The decision was made to spec out part of a Roadster Shop chassis. Basically, it was their Slammed C10 chassis, but completely naked out back. We knew it was going to get something special-a Cortex Racing watts link for the s197 mustang 8.8 going in. Check out the pictures and descriptions below to see the rest of the goodies: Ford performance Coyote crate motor, Performance Automatics 4r70w with a Powertrain Control Solutions paddle shifter and GSM, Rotiform custom 3 piece wheels, Bed Wood Brazilian Cherry bed floor, Vintage Air HVAC, MIshimoto radiator and coolers, Power By the Hour accessory drive, Wilwood Aero 6/4 front and rear brakes, Top Stitch Upholstery custom interior integrated into the roll cage, paint by Damn Straight Customs.

The first step on a project of this scale is to get the motor/tranny, chassis, and cab on the fixture table. Once everything is roughly in place, then start to dial it all in based on what you want the end result to look like. Here we got the motor and trans positioned in relation to the cab and hood, which locates the grill. Grill location in relation to the front wheels was the priority because of the look the customer was after. Our 18' chassis table was built in house and is infinitely adjustable with T channel extruded aluminum framework. It's not uncommon to built 90% of the fixtures for a project (seen here supporting the cab), which allow it to be moved around easily to dial in mounting.
Once the cab and drive train are in place relative to each other, we can fabricate motor mounts, transmission crossmember and body mounts. The rusty old floor and rocker panels were completely cut out and replaced with a 1x1 structure that will be a solid building ground for the body mounts, cage mounts, and sheet metal.
Tackling the last of the rusty stuff was the next step. While most of the rot had been cut out with the floor, firewall, and rockers, the bottoms of the pillars were another issue. Being these pieces are not available from the aftermarket, and it is crucial they are in the right spots for the door gaps to be correct, they had to be painstakingly hand formed. From the pocket for the hinge, to the captured nut plate on the back and the step in the face for the quarter panel and cab corner to sit in. These are the details that if done right, will never be noticed or appreciated after it's all said and done!
The rear chassis section of the Roadster Shop chassis was highly modified. Roadster Shop offers great options for rear suspension, but we wanted to run the Cortex Racing watts link setup that we have come to be very familiar with on the mustangs. We also knew the wheel base was not going to match what we were doing, which would require further modification. The chassis was cut and extended 11", then plated, the C-notch was cut and lowered by 4" because the chassis was intended for a laid out air ride application. The axle housing was stripped and brackets were fabricated for the link bars and coil overs. The Fuel Safe fuel cell was also mounted. Bladder cells are not cheap, but it's not worth risking a fire due to a ruptured tank-don't take safety lightly!
This is where is all starts to come together! The 1x1 floor structure is cut and bridged for driveshaft/trans tunnel clearance, then the sheet metal can start going down. The 1 piece firewall was fit up, then removed for bead rolling, same with the floor boards. After they were in, the 1.75" x .134" wall DOM cage was bent up and wrestled in to place. After that, pedal assemblies could be mounted. The plastic/aluminum cover on the Ford drive by wire accelerator pedal didn't match the pad we made for the brake pedal so we removed it and made a matching one-its all in the details!
Being Gramps is fenderless and the frame rails from are not the most eye catching, a set of spaghetti inspired, true equal length headers were fabricated to fill the space. Also keeping with the theme the cage gives the interior, a tubular structure was built to house all the electronics and double as a center console. A custom seat bracket mounts the Corbeau bucket seat. The "bed floor" bed cover frame was also finished, powder coated and had the Brazilian Cherry planks installed. This will lift on gas struts like a "Tonneau cover", giving access to everything underneath.
The front of the Roadster Shop chassis was meant to mount a bumper to and stuck out past our grill. We cut the tips of the rails off and made a drop piece to mount the radiator and grill to. The grill itself was one of the biggest challenges of the build. The top piece integrates into the fenders and is much wider than the lower slat portion, but it also blend the shape of the hood into the shape of the slats so we had to use it. After multiple revisions and a new top piece from LMC, the crew came up with something that looks great. Blending our style of building with some triangle dimples and spiked tubular crossmember, with some more classic hot rod sheet metal work, the end result is a great looking front statement piece...at least in our opinion.
