105.64 and 105.65 Montreal identifiers
Alfa Romeo Montreal VIN Decoder
The Montreal uses 105.64 for the main LHD family and 105.65 for RHD production, making the type identifier particularly useful for collector records.

Decoder reference
What this decoder page is designed to answer.
The Montreal has a particularly useful Alfa type split
Factory production records distinguish the main left-hand-drive Montreal as type 105.64 and the much smaller right-hand-drive family as 105.65. When that type is entered with the chassis serial, PetrolJunky can confidently identify the Montreal and preserve the market-family clue in the registry.
Production span is not the same as an exact chassis year
Montreal production is documented across the early-to-mid 1970s, but the type code by itself does not convert every serial into a precise build date. The decoder therefore returns the correct model and documented production span while avoiding an unsupported exact-year claim.
Useful for high-value provenance
That conservative distinction matters on collectible cars. Registry photos, ownership history and factory documentation can later add the exact build details without overwriting what the chassis/type identification actually proves.
