in addition to the VIN match did the engine code stamp match, L for base engine X for L82?
CKZ 1977 350 L48
CLA 1977 350 a/t L L48
CLB 1977 350 m/t, high altitude L L48
CLC 1977 350 a/t, Calif L L48
CLD 1977 350 m/t, high altitude X L82
CLF 1977 350 a/t, Calif X L82
CHD 1977 350 a/t, Calif L

Did you check the transmission for a partial VIN and the correct code?
Code Transmission
W Warner 4-Speed, Heavy-Duty Aluminum Case
AM Turbo Hydra-Matic 350 with 350 L-48 Engine
CB Turbo Hydra-Matic 400 with 350 L-82 Engine

Differential Codes
Code Ratio
OA 3.08
OD 3.36
LR 3.36
OB 3.55
OC 3.70
