Corvette Parts Manual

What is in the parts manual

This is the factory parts catalogue, the book a Chevrolet dealer's parts counter worked from. It is not a repair manual and it will not tell you how to do a job. What it does is list every part Chevrolet fitted to a Corvette, with the part number, the years and models it applies to, and an exploded illustration showing where it goes and what it goes with.

That makes it the reference for two jobs in particular. The first is ordering the right thing: a part number from this book removes the guesswork when a supplier lists three similar items and only one fits your year. The second is putting something back together correctly. The illustrations show the order of washers, spacers, clips and brackets, which is exactly the information that goes missing when a car has been apart for a few years and the box of fasteners no longer means anything.

What it covers

The catalogue spans C1, C2 and C3, which means 1953 through 1982 in one set of books. For C3 owners that is useful in both directions: it covers your own car, and it shows where a part carried over from an earlier generation or changed partway through the run.

It is split into six files here purely so each download stays a manageable size. Nothing is left out. If you are looking for specification figures rather than part numbers, the specification manuals are the other half of this set, one book for each model year from 1968 to 1982. To identify what your car actually is before you start ordering, use the Corvette VIN decoder and the RPO option code decoder.

Things we found while reading it

A parts catalogue sounds like the driest book ever printed, and page for page it is. But because this one covers thirty model years in a single set, it quietly records what Chevrolet reused, what it fussed over, and what it quietly dropped. We went through it. Here is what stood out, with the part where we found it so you can look for yourself.

One knob, three jobs, same car

Part number 3846934 is listed as the inside door lock knob for 1963 to 1974. Turn to the same subgroup and there it is again for 1977, this time as the knob on the seat adjuster lever, and again as the air vent control knob on cars without air conditioning. One casting, six and a quarter dollars, doing three unrelated jobs on the same car. If you have ever thought your vent knob looked oddly familiar, that is why. Part 5, group 10.512

A spring that outlived two generations

In the same subgroup sits retainer spring 4168122, listed for 1956 to 1963 and then again for 1967 to 1977. The later entry adds a note that it is now the steel snap-on type, but the number never changed. A part first fitted to a solid axle C1 was still going into cars with rubber bumpers and catalytic converters twenty years later. Part 5, group 10.512

The compass that never changed

The accessory list has a dash compass, part 983335, with a single line against it: 1953 to 1982. One part number for the entire run of the book, across three generations of Corvette, with not one design break recorded. Compare that with the door lock cylinders a few pages away, which needed a new part number almost every single year from the mid seventies on as key coding changed. The humble compass outlasted them all. Part 1, group 21.100 and Part 5, group 10.550

Chevrolet's own paperwork admits there was no 1983

The front of the book lists every parts publication Chevrolet issued. Number 14A is this one, the 1953 to 1982 Corvette catalogue. The next Corvette entry is 14Y, the 1984 catalogue. There is nothing in between. The missing 1983 Corvette is not just an enthusiast talking point, it is a gap in Chevrolet's own filing system. Part 1, front matter

You can watch the vent windows disappear

Look up the door ventilator parts and every one of them stops dead at 1967: the ventilator assembly, its weatherstrip, the channel, the regulator, the knob, even the rivet. The 1968 car did away with wing windows, and the catalogue records that as a column of entries that simply end. While you are there, spare a thought for part 4155046, the vent catch knob, which was listed for 1953 to 1955 and never again. Part 5, groups 10.650 to 10.669

The last years got oddly domestic

Late in the run Chevrolet was selling the Corvette a trailer hitch ball, in two diameters, for 1980 to 1982. It was also selling a ski adapter that clipped onto the roof panel carrier, for 1982 only. And for that same final year there was a body side pinstripe kit, supplied as two nine foot rolls, in a colour the book calls dark redwood. Part 1, groups 21.060, 21.250 and 21.450

Twenty shades of one plastic ring

The escutcheon is the little trim ring that sits around the inside door lock knob. For the 1978 to 1982 cars it was stocked in roughly twenty colours per side, from saffron and doeskin to midnight blue, oyster white, dark claret and silver green, so it could be matched to the interior trim code. Four dollars seventy, and a colour chart to rival the paint. Part 5, group 10.515

How much is hidden in a single line

Near the front there is a worked example the parts counter staff were meant to study, and it is worth a look before you use the book in anger. It takes one ordinary line for a pedal push rod and picks out eighteen separate pieces of information packed into it: model year, body usage, engine and carburetion, option code, transmission code, part number, quantity, the noun name, exceptions, design breaks, air conditioning and limited slip codes, dimensions, trim combinations, paint instructions and more. Once you have seen that, the dense columns start to make sense. Part 1, Chart A

A warning that dates the book perfectly

The title page carries a stern notice that cars from 1976 on contain many parts dimensioned in metric, that metric and inch fasteners look almost identical, and that mixing them can cause damage or injury. Chevrolet even issued dealers a red label reading "Metric Fasteners Required" so the counter staff could spot them. It is a small thing, but it captures an industry halfway through changing its measuring system. Part 1, title page

One caveat on all of this. These pages are photographs of microfiche, not searchable text, so we read them by eye rather than by machine. If you find something we got wrong, or a better oddity of your own, the contact page is open and we will happily correct it.
