Body-on-frame construction (Body-on-chassis, not unibody), reinforced passenger cell for the era.

💡 Technology Features

Radio Options:

Factory fitted AM/FM radios, often with optional 8-track tape players on higher trims. Catalog will list radio bezels, knobs, and aerial components.

Era Features:

Basic driver aids. Features like power steering were optional on lower trims but more common on V8 models. This catalog lists steering boxes, linkages, and pumps.

Vehicle Systems:

Focus is on mechanical and electrical component connectivity for vehicle operation; no modern electronic connectivity features.

🔧 Maintenance

General Guideline:

While this is a parts catalog, typical intervals for the era included oil changes every 3,000-5,000 miles (5,000-8,000 km), with more extensive checks for cooling, ignition, and transmission fluids at similar or slightly longer intervals. Consult a dedicated service manual for precise schedules.

Engine Oil:

SAE 20W-50 or 10W-30 depending on climate and engine type. API SF or SG service classification recommended (though early specs may vary). This catalog lists oil filters and associated seals.

Coolant:

Ethylene glycol-based antifreeze/coolant mixture. Catalog will list radiator hoses, caps, and thermostats.

Common Wear Items:

Parts listed in this catalog would cover common wear items such as suspension bushings, brake pads/discs/drums, steering components, engine gaskets, water pump, and exhaust system parts. Rust and body panel integrity are also typical concerns for vehicles of this age.

📚 Vehicle History

Holden Legacy:

Holden's significant Australian automotive manufacturing history, known for creating robust vehicles suited to local conditions.

Torana Lineage:

The LH Torana was a significant step up from the previous LC generation, offering a more substantial platform and a wider range of engines, including powerful V8 options. The SLR5000 and L34 were performance flagships.
