Chassis Identification

In 68 they used the fender tag SO number to match the core support and left rear quarter panel numbers. If one is off see if the other jives.

There is No definitive way to tell for a 68 if you have no
build sheet - has all info needed
fender tag - has body info, but no VIN
certicard - has VIN and build date and some other info that should match up with Fender Tag.

When this info is missing and being sold as a value car you need to price accordingly. For 67 and earlier you can order the build card from Chrysler Historical. A fire and the water used to extinguish it in the Chrysler records storage building took out all the records from 68 on.
