DECODING THE 1957 IMPERIAL DATA PLATE
This plate is attached on the upper right hand radiator support. Sometimes removed or swapped by owners, body or paint shops or unscrupulous individuals!
I've picked the following info from the CHRYSLER 300C Handbook and also applies to the 1957 Imperial.
Example of data plate (prior to entry of production information):
Above the first line you'll read numbers or letters related to this line:
MDL = Model: I don't have the codes yet. I know only that 283 = Crown convertible and 289 = Crown Southampton four-door hardtop.
PNT = Paint code: A = Jet black etc.. (see below). Z or ZZ = special order paint (1 or 2 colors)
TRIM = Trim & upholstery, no info. 00 = special order interior
SCH = Schedule date: month / day. i.e 0403 = 3 April (57)
ITEM = no info
BODY= # body?
SO/FO= Special order/foreign order. If there's a number above you have a rare or foreign car!
The double rows of small numbers are to be read from top to bottom. If a third and larger number is printed in a vertical column, the car was produced with that option code item. For example, the firsts of the lines are 3 & 5. If you've under the 5 the number 7, the code option is 357. This code applies to all 57 Chrysler products and some of them aren't used on Imperial because they are standard (i.e Torqueflite) or N/A.

Example of my car (57 Crown convertible):
Options I have: 357, 344, 349, 224, 356, 345, 323, 265 (?), 358, 332. Schedule: 11 / 8 (56) or 1 / 18 (57) ? I think 1 / 18 because 57 Imperials were introduced 10/30/56 and my serial number is C57 9909. If it was built in Nov. 56, the number would be a C57 1... or 2....
