Why do you think such a database exists? You're talking about "the" database, so I assume you not only think there is one, but know which one it is also.
Most databases can't be downloaded, so I think it's unlikely this one can be downloaded. But since you seem to know it, just ask the owner how to do it.
Where can I download the database of car parts with weight for each part?
