The buy out of Chrysler by FIAT has resulted in many changes to the Chrysler administration system.
The old Walter P Chrysler archives no longer operate as such but FCA have set up a new (and easier) way of getting build cards or records for your vehicle.
Here is the form to apply for a build card for most Chrysler products up to the mid-50's for trucks and 1967 for cars. The build sheets not only are an historic addition to your vehicle history but tell you what the original specification was.
