The Summit Racing plastic bucket seats and G Force Racing Gear harnesses are also tied in to the 'cage for added safety. In order to allow more legroom, the rear fenders were tubbed and the seats were shoved rearward before Herculiner was applied to the interior and under the tub. The exterior of the flatfender was sprayed with Royal Blue paint and fitted with custom diamond-plate corners that Sumner built himself.
The engine is a 350 Chevy with a host of Edelbrock parts and is cooled by an AFCO aluminum radiator and electric fan. | 
A full-width Dana 44 from a Chevy truck was used up front. | 
The stock dash was replaced with a custom aluminum piece that houses Auto Meter Phantom gauges. |
The seat mounting required the stock gas tank to be scrapped, so Sumner mounted a 20-gallon aluminum fuel cell between the rear wheelwells along with an Optima RedTop battery. A rack was integrated into the 'cage above the fuel cell to both protect it and provide a place to store tools, spare parts, and lunch on the trail. Other interior features include the hanging pedals from a Wrangler, a custom aluminum dash with Auto Meter Phantom gauges, and an aluminum quick-release hub for the Grant steering wheel.
The thing that we like most about this vehicle is the great attention to detail. From the properly placed bumpstops to the clean wiring, Sumner took no shortcuts. That said, he still plans to swap out the carburetor for a TBI setup and replace the current wheels with Hummer double beadlocks to alleviate concerns about losing a bead. But after building for five years on a college student's budget, those details can be sorted out later. For now, Sumner is just enjoying himself out on the trail.
The square-tube driveshaft is cheap, strong, and provides plenty of slip travel. | 
The 20-gallon aluminum fuel cell sits between the rear wheelwells and is plumbed with Earl's aluminum fittings. | 
The rear axle is a Corporate 14-bolt with 5.13 Yukon gears, a Detroit Locker, and disc brakes. |
 | 
The rear bumper was built with the taillights enveloped in steel rod to keep them from breaking. | 
The column is connected to an aluminum quick-release hub and topped with a Grant steering wheel. |
