Technical Advice & Instruction Manual Library

Our team have collectively been building awesome custom american trucks and cars for many years. During this time, they have gathered together a wealth of technical knowledge and instruction manuals for the various components that feature in our builds.

In the spirit of sharing and giving something back to the community, we will add to this page regularly and hope that it will assist you with some of the common questions we are asked or simply to provide instruction manuals to help keep your custom vehicle on the road.

History of the Chevy truck

The Advance Design series of pickup truck, and more specifically the 3100 1/2 ton version, was sold between 1947 and the first part of 1955. This is also known as a ‘first’ series. The cabs were offered with a standard 3 window or a deluxe 5 window arrangement that assists the driver when reversing or checking blind spots.

First Series 1947-1953

There were a number of subtle changes and enhancements throughout this period such as the location of the gas tank, non-vented and vented side windows, exterior door handles that initially turned downwards then later featured a push button and an 8 or 9 board bed.

A 1947-53 truck front end:

First Series – 1954

The ’54 truck was a one year only production and had a number of new features including a one-piece curved windshield, a new crossbar ‘bull nose’ grille design, revised steering wheel and dashboard.

A 1954 truck front end:

First Series – 1955

Similar to the ’54 truck with the exception of a redesigned hood emblem and a more modern driveshaft to power the rear wheels rather than the earlier torque tube.

Second Series – 1955-1959

The ‘Task Force’ or Stepside second series was the successor to the Advanced Design first series truck.

Featuring an all-new body style, new wrap around windshield, power steering and brake options and 12v electrics from the factory.

A second series truck:

Again, there were a number of subtle changes and improvements throughout the production run including emblems.

Most notably in 1958 the truck rear load area or ‘buck’ was now offered in a fleetside design. The trucks were also known as an Apache and featured twin front headlamps.

Last year of manufacture for these trucks was 1959.

At the end of ’59 the second series trucks were replaced by a C (2wd) and K (4wd) replacement –  this ran through until 2002 in a number of generations.

The serial numbers for 1947 through 1955 US made Chevrolet Advance Design trucks are 8 to 12 digits long*. They are comprised of two sections. The first section ends with the last alpha character. It is arranged in one of two distinct formats, depending on the year the truck was built, as explained below. The second section, all numeric, is the plant production number, with the first truck built at a given plant receiving the number 001001.

Wheel Fitment

Being rebellious is all about showing that desire to resist authority, control and convention. It’s thumping V8s, burning rubber and rock music. It’s the ultimate expression of personal freedom in a world of endless rules and regulations for those who enjoy classic muscle cars, love what they stand for and the way of life that era represents. It’s about styling, substance and attitude that only vehicles with a muscular persona and cool heritage can deliver.

Dynamat Sound Deadening

Dynamat Xtreme is a black butyl based core with 4 mil aluminium layer and craft paper release liner.

We install this within the cab floor area to drastically reduce noise and vibration. It can also be used inside doors, on the bulkhead and rear of the cab behind the seats.

It is installed directly onto the metal panels of the vehicle and is self adhesive. It can easily be cut to shape or fitted as a full sheet. The best way to install this is with a wallpaper roller, after cleaning the surface, to ensure it is well stuck down.
