Car enthusiasts love old school vehicles. There was something unique about them. The making was not like it is today, of course. Build sheets are something that takes us back to that time. They were during the vehicle had to be assembled. It was used as a tool to communicate with the workers. What needs to be fitted on the vehicle and what was used on the Trim and Chassis (T&C) line, are pretty vital questions. Once the vehicle had been completed, they would then dispose of the build sheet. If not that then often they were placed in the car. Some of the best spots you can find build sheets are under the carpet, behind the door panel, inside the headliner, stuffed in the seats etc.
In the pre-1967, the typical build sheets were not as detailed as the ones that came later. Yet, they had codes for most of the options and parts assembled on or in the vehicle. Codes that are used for the different parts of vehicles have to be read by someone who clearly understands it. A layman will not be able to translate those codes and make sense out of them. Typically, things like driveshafts, shocks and springs were colour coded to identify each of the items. The reason behind this was that parts had a similar appearance while they were different in engineering value. An example of this is that two springs might look very similar but were significantly different so they would be painted with dots or lines to make the differentiation easier.
