Could a "jerry-rigged" fuel repair turn your Avanti into a fire hazard? For owners of 1974–1985 Avanti II models, an improper fuel line modification is more than a mechanical eyesore—it is a recipe for an engine fire. In this urgent safety guide, Dan Booth explains why the common practice of cutting steel lines to add inline filters or rubber hoses is extremely dangerous.

Why are Avanti gauges notoriously difficult to read at night? The answer lies in the evolution of "gang lighting" and factory design changes over 22 years of production. In this expert guide, Dan Booth explores the four distinct styles of red dash lighting used from the original 1963 Studebaker Avanti through the final 1985 models.

Installing an exhaust system on a 1963–1985 Avanti is a notorious challenge, requiring precise clearances around the steering control valve, oil filter, and X-member frame. In this definitive guide, Dan Booth explains why generic muffler shop pipes often fail and why authentic, blueprint-bent components are the only solution for a rattle-free fit.

Struggling to see what's behind you in your Avanti? The combination of a tiny original mirror, a low-mount position, and the classic "Avanti Rake" creates a notorious blind spot for drivers. In this guide, Dan Booth explores the evolution of the Avanti mirror from the 1.5-inch Studebaker originals to the modern 1980s Day/Night versions.

Have you ever experienced a mysterious "hammering" sound coming from the rear of your Avanti during acceleration or braking? This is often caused by a broken front mounting stud on the frame bracket for the rear axle radius rod. While many mechanics assume this requires a complex frame repair, Avanti Motors actually engineered a specific solution.

Are you 100% sure your brake lights work every time you hit the pedal? The original hydraulic pressure switches (Part #666858) used on 1963–1973 Studebaker Avantis and Avanti IIs are notorious for short life expectancies and heat-related failures.

Following our initial safety alert regarding the 60-year-old rubber steering rag joints, Avanti owners across the country began inspecting their own cars. The results were startling. In this follow-up, Dan Booth shares the feedback from readers who discovered their steering was "holding on by a thread."

Are your Avanti's brakes constantly "on" or wearing out pads prematurely? The culprit might be a hidden mismatch between your power brake booster and master cylinder. In this guide, Dan Booth reveals a common factory oversight involving the reach rod end.

If you own or drive a 1984 or 1985 Avanti, your front wheels could be at risk of coming off while driving. Specialist Dan Booth reveals the hidden history of a dangerous factory oversight involving the one-inch aluminum wheel spacers used during the Stephen Blake production era.

Replacing a leaking A/C evaporator core in an Avanti is traditionally a nightmare job requiring the removal of the entire dashboard or the complete heater assembly. In this technical guide, Dan Booth shares the "unthinkable" shortcut he has used for over 40 years: a strategic diagonal cut to the fiberglass console that makes this repair significantly easier and faster.

Does your Avanti suffer from the dreaded "leaky roof" reputation? While many believe factory sunroofs are destined to leak, specialist Dan Booth reveals the unknown facts behind the American Sunroof and Sky Top systems used from 1971 to 1985. Properly maintained, these units were originally trouble-free—and they can be again.

Did you know that most 1974–1983 Avantis are pre-wired for fog lights right from the factory, even if the option wasn't chosen? In this technical guide, Dan Booth traces the history of Avanti Motors' auxiliary lighting. From the original $50 "Do-Ray" option in 1967 to the iconic Lucas, Cibie, and Hella lamps used throughout the Altman and Newman eras, learn how to identify the correct brand for your specific year.

Is your Avanti heater core leaking or your blower motor squealing? Don't let a complex-looking dashboard discourage you from a comfortable ride. In this detailed guide, Dan Booth breaks down the professional method for removing and reinstalling the heater assembly for all 1963–1985 models.

Does your 1984 or 1985 Avanti sound like "somebody is building a house in the back seat" when you turn on the heater? You aren't losing your marbles—you're likely experiencing a factory engineering oversight. In this article, Dan Booth recounts how he discovered a reversed valve installation that caused a notorious hammering noise in new Avantis, leading him to modify over 100 factory units.

Are your Avanti sun visors rock-hard and heavy? If so, they aren't factory correct. Drawing on original Studebaker blueprints and his background as a journeyman toolmaker, Dan Booth sets the record straight on the three distinct styles of sun visors used from 1963 through 1985.

Imagine being stuck on the blind side of a curve at dusk with no way to warn oncoming traffic. For owners of 1963–1964 Studebaker Avantis, this nerve-wracking situation is a real possibility because these early models were built before 4-way flashers were federally mandated.

Is your Avanti's inside door handle feeling "lazy" or failing to snap back into place? This is a common sign of a broken return spring in the remote control assembly (Part #1350543/542). More than just a minor inconvenience, a weak spring can prevent the door from latching completely, creating a serious risk of the door swinging open during sharp turns or sudden stops.

Are your dome lights failing to turn on when you open the door? The problem might be more than just a bulb—it could be an incorrect or improperly grounded door switch. In this technical deep-dive, Dan Booth uses original Studebaker factory blueprints and 45 years of experience to identify the correct switches for every production era

After decades of exposure to the elements, the seat mounting bolts in many 1963–1985 Avantis eventually rust and snap off. Because the original Part #1351038 nut plates are sandwiched inside reinforced fiberglass, a simple extraction is often impossible.
