GM Body Style Codes

Here are the 2002 codes and information.

Until about the later 1970s, the various GM body series' letter designations were not prevalent in their parts books. For example, a '70 Chevy Impala/Caprice/et al was "Passenger", Chevy II was "Chevy", Camaro was "Camaro", Chevelle was "Chevelle", Monte Carlo was "Monte Carlo", and the Buick parts books used the basic VIN series numbers (i.e., 4000 = Special, 5000 = LeSabre/Wildcat). As for Chevy engine designations, there were usually the normal 6 cyl and 8 cyl deals, 2bbl and 4bbl, but past that it was "code" . . . 327/300 = 327 4bbl dual exahust, 327/350 = SPE (special performance engine), 327/365 = SHPE (special high performance engine), 327/375 = FI (fuel injection), and the L-88 427 = 427 HD.

In the front of the Chevy car parts book, there was a listing of every model and it's VIN designation, which was broken down in series, trim level, body style, and 6 cyl or V-8. Later, this was done in more of a chart. As for telling which engine the vehicle had from the VIN . . . the engine digit was either "even" or "odd" (I don't recall which one was 6 cyl or V-8), with no specific list of which engine matched which code number (although some seem to have another source which decoded that in the pre-1970 model years).

As I recall, the 1969-87 Grand Prix cars were all G-cars, as were some Olds Cutlass Supremes. I don't recall any Chevy's having G-designations, even the Monte Carlo, other than as a "trim level" of Chevelle (as in AG87 for a Monte Carlo, which were all 2-dr hardtops).

In the later listings, the Camaro was listed as both "F" and "T". ONLY the "F" designation is accurate. "T"s were only Chevettes and Pontiac T-1000s--period.

Thanks for that link, Mr. Earl.

Enjoy!
