Ferrari 308 GTB, 308 GTS 1978 Parts Catalog – Factory OEM

If you’re ordering parts for a Ferrari 308 GTB, 308 GTS 1978 Parts Catalog without the factory catalog, you’re wasting time and risking the wrong component. I’ve seen guys order a water pump only to find out the U.S. version uses a different pulley. This catalog gives you the part numbers straight from Ferrari’s Technical Assistance division – July 1978 print. It’s 150 pages of exploded diagrams and classification numbers. You don’t guess; you match the drawing to the part on your bench.

What Does the Ferrari 308 GTB/GTS Parts Catalog Actually Cover?

The catalog is organized by vehicle systems – engine, transmission, suspension, electrical, body. Each section lists parts with their Ferrari drawing number, quantity per car, and notes. Need the exact part for the 308 GTS targa top seal? It’s in there. The 1978 U.S. version specific components are called out separately. This isn’t a generic aftermarket list; it’s the original OEM print from Graphotecnica Maranello, cat. 161/78.

Ordering Parts Correctly: The Three-Digit Code

Page 3 of the catalog spells out the ordering rules in Italian, French, and English. You must quote the denomination, the classification number from the catalog, and the engine and chassis numbers of the car. Period. If you skip the chassis number, Ferrari’s system will likely ship the wrong part – or reject the order entirely. That’s the difference between a restoration and a parts swap.

How to Use the English, Italian, French Text

Every page has three columns – one for each language. The part denominations are given in Italian first, then French, then English. If you’re an English-only speaker, you read the bottom line of each entry. The abbreviations are also in Italian: Dx (right), Sx (left), GD (right-hand drive), GS (left-hand drive), AC (air conditioning). For a U.S. version 308 GTS, you’re looking for GS and Sx/Dx depending on side. Don’t mix them up.

OEM vs Aftermarket: Why Factory Part Numbers Matter

Aftermarket parts catalogs often list generic or superseded numbers. This catalog gives you the original Ferrari drawing number from 1978. If the part is discontinued, you need that exact number to search for NOS stock. The catalog also includes a note that descriptions and illustrations are not binding – Ferrari reserved the right to change components without updating the catalog. So you cross-check with the actual part on your car. That level of traceability is why I trust factory documentation over any third-party list.

Ferrari 308 GTB and 308 GTS 1978 Parts Catalog: A Professional’s Breakdown

I’ve used this catalog to locate a set of correct fuel injector seals for a 308 GTB. The U.S. version injectors are different from European – the catalog shows the right part number under the “fuel system” section. Without it, I’d have ordered the wrong ones and lost a weekend. The electrical section includes the battery terminals; for general battery specs, see Automotive Battery. Ferrari’s production in 1978 was part of the broader Automotive Industry Overview shift toward emissions compliance. This catalog captures that era’s parts.

FAQ

Does this catalog include torque specifications?

No, it’s a parts catalog, not a service manual.

How do I find the part number for the 308 GTS window regulator?

You locate the body section, find the window system diagram, note the reference number, then look up the classification number in the parts list. The catalog uses a cross-reference system where each part has a drawing number and a catalog number. You must also check the model variant – GTB or GTS – because some parts differ. If you have the original glass or could measure the regulator, cross-check with the diagram. The catalog also includes quantities per car, so you know if you need one or two. That said, if the part is not illustrated, you may need to consult the workshop manual for disassembly to confirm the exact component.
