Model year 1977
1977 Corvette Interior Colors and Trim Codes
1977 is the first year leather was standard rather than an option, so the chart below reads differently from every year before it. Seven interior colours were offered, in full leather or leather with cloth inserts.
1977 interior trim codes
| Interior colour | Leather/Cloth Inserts | Leather |
|---|---|---|
| White | not offered | 112 |
| Smoke-Gray | 15C | 152 |
| Black | 19C | 192 |
| Dark Blue | 27C | 272 |
| Buckskin | 64C | 642 |
| Dark Brown | 69C | 692 |
| Medium Red | 72C | 722 |
How to read your trim code
From 1975 the trim code carries a letter that tells you the material at a glance. A code ending in V is vinyl and one ending in C is cloth, while an all-numeric code ending in 2 is leather. So 19V and 192 are the same black, one in vinyl and one in leather. Read the code off the trim tag riveted to the driver's side of the body, just inside the door opening, alongside the paint code. It is the only surviving evidence of what the car originally had once the seats have been recovered.
What each 1977 interior came with
This is the same factory chart the 1977 colour page carries, turned round. That page starts from the paint and tells you what could go inside. This one starts from the trim code, which is the way round you need when you have read the tag and want to know whether the car left the factory in the combination it wears now.

Seats and trim in 1977
Leather became standard equipment in 1977, with cloth inserts as the alternative rather than the upgrade, which is why there is no custom interior option on the 1977 list. The console was redesigned so the radio sat higher and easier to reach, the wiper and washer controls moved to the turn signal stalk, and the door panels lost their map pockets.
The interior chart for every model year from 1968 to 1982 is on the C3 interior trim page. The exterior paint codes for this year, with how many cars wore each colour, are on the 1977 colour page, and the full option list is on the 1977 specifications page.
