There's something about a restored older base-model truck that's really neat-neat to look at, that is. When it comes to overall performance and over-the-road practicality, standard-equipped trucks leave a lot to be desired. In fact, even a fully loaded stock Silverado leaves plenty of room for improvement
The '74 Chevy shortbed stepside featured here belongs to CCT's associate publisher John Barkley. Some of our regular readers might recognize it from previous tech articles. For those of you who are new readers, we'll bring you up to speed
In February 2005 John bought his truck from Todd Ryden at MSD Ignition in El Paso, Texas. The purchase price didn't include shipping, and besides, it was a good excuse to get in a road trip. John and his son Greg hopped on a plane to El Paso to drive his plain-Jane Chevy home. When Todd told John the truck was stripped he wasn't kidding-never mind a radio; it didn't even come with a cigarette lighter or a dome light.
The duo had hardly made Interstate 10's onramp leaving El Paso before John was making mental notes on what he would like to improve first. Right from the showroom floor, six-cylinder Chevy pickups weren't what one might define as freeway fliers, and with 30 years on the clock John didn't want to blow this one up. Fearing the little 230-inch motor might throw a rod right through the floor and take his foot with it, John kept the speed right around 60 mph. Even at this low speed, without any real soundproofing to speak of the truck's cab sounded like several cats on a hot tin roof. When John returned to California, he remedied the truck's asthmatic performance by dropping in a 355-inch small-block from Speed-O-Motive with Edelbrock heads and intake. (See the June '04 Super Chevy for more details.) To bring the revs down, John yanked out the three-speed stick tranny and installed a TCI four-speed automatic overdrive 700-R transmission. The powertrain swap helped big-time with power and it brought up the cruising speed, but the '74 was still too noisy. There was just no way to get around it; John's truck needed some serious help on the acoustic side. The first step in doing a first-class soundproofing job is to begin with a top-quality kit. In our Jan. '06 issue, John's base-model '74 got the full Quietride treatment. This was a great start, but in addition to insulation and good acoustics, John wanted to bring his truck's interior trim level up beyond a stock Silverado.

From any angle it's hard to...

From any angle it's hard to tell this plush Silverado-style custom interior was once an ordinary standard-equipped plain Jane. Read on and find out what it took to make such a radical improvement.

The '73-87 Chevrolet truck...

The '73-87 Chevrolet truck padded dashboard cover is the easiest one in the world to remove. We located the Phillips head screws placed at the lower front edge of the padded dash and on top of the dash bezel, then removed them. Afterward, John checked to see that he hadn't missed removing any screws by lifting the dash pad upward away from the white painted-steel dashboard. With the dash pad free, he was then able to pull it toward him until it came off.

Here's a top view of the new...

Here's a top view of the new black dash pad from LMC Truck in comparison to the Texas sun-trashed original Chevrolet blue dash pad.
The transformation of John's '74 from a stark plain Jane to a plush custom was almost a one-stop endeavor. The LMC Truck catalog had almost everything, except the black Corbeau Sports seats and the steering column.
To locate his seats John went onto Corbeau's website and found a dealer near him. For the automatic tilt column he went to Golden West Auto Wrecking in Westminster, where they got lucky and scored a complete set of Silverado window moldings, too.
Machining an engine or straightening a frame might be something best left to the experts, but when it came time to install John's interior, he felt the best way to illustrate tech tips for CCT's valued readers was to do it himself. It makes sense; after all, how can we show you guys how to avoid the pitfalls if we don't discover them ourselves?

John removed the six retainer clips from their envelopes and placed them handily near the dash pad. Clear packaged hardware and silver-plated screws below are included for the LMC Truck kick panels and Silverado door panel kit.

With the dash pad placed upside down on a soft towel to prevent scratching its surface, John was ready to slide the retainer clips forward to snap in place. The first ones were a little tricky, but John soon learned the knack to attaching them.

A properly installed retainer...

A properly installed retainer clip should look like this. We discovered that by spreading the retainer clip slightly more open, it allowed the clip to slide over the slots with thicker coatings of black plastic dash pad material.

John installed the new LMC Truck dash pad by placing it over the gauge cluster (driver side) and dashboard (passenger side). He then shoved it forward while holding it pressed down tight against the dashboard's white painted metal top until the clips hooked into place. The passenger side screws were then refitted.

The next step was to replace the dash bezel with a new one and screw it back into place, but John discovered he had ordered the wrong part.

Always double-check that you have ordered the right parts. In addition, we learned that LMC Truck catalogs make great reference material and should be kept on hand any time one works on their truck.

The beauty of Corbeau is it sells over-the-counter custom-made seat brackets to adapt its bucket seats to a wide variety of vehicles. Corbeau's factory-applied part number tag makes it very clear these are the right brackets to replace the stock '73-87 Chevy bench seat.

Corbeau seat brackets utilize...

Corbeau seat brackets utilize the three existing stock holes to mount its seats, requiring only one new mounting hole to be drilled. This time-saving design makes Corbeau seats virtually a direct bolt-in replacement.

Note the seat mounting points...

Note the seat mounting points (holes) parallel to the uninstalled dash pad on the floor. Only two extra holes had to be drilled here. Installation tip: We used a large drift pin to align the Corbeau seat brackets to the seat mounting holes, and utilized the seat bracket as a template to drill the fourth hole.

John procured a Grant mahogany steering wheel from LMC Truck. It was necessary to buy the steering wheel installation kit, which includes a horn button, a die-cast steering hub, Grade 5 bolts, and instructions. A steering-wheel puller was needed to remove the original stock wheel.

John's next step (with Jason's help) was to install a fabric-covered ABS plastic replacement headliner from LMC Truck. There are two styles available; one is for trucks that did not come with a factory-installed headliner (such as John's base-model C10), and the other is for trucks with a factory-installed fiberboard headliner. In order to use an OEM (factory-style) headliner, John had to obtain Silverado window moldings to hold it in place.

Mistake alert! At first we...

Mistake alert! At first we tried to poke holes through the headliner material covering this triangular hole matching the shape of the sun-visor mounting bracket. The right way was to use a single-edged razor blade and trim out the triangular hole.

Our next error was to mix...

Our next error was to mix up the left and right sun visors. We failed to notice the L and R markings on the backside of the brackets, signifying side placement. This was a basic mistake that wasted valuable time and could have left irreversible scars on John's headliner.

After a few derailments we were back on track. The key to installing the LMC Truck sun visors was to make sure the holes lined up and the screws were tightened down evenly in rotation.

Another factor that slowed...

Another factor that slowed us down was the additional insulation on the ceiling, causing the headliner not to seat all the way. Thanks to keeping our cool and not tying to force it we were victorious in the end.

Before installing the Silverado...
