Details:

This has a significant impact on part numbers since current inventories could not have price increases. This item is New Old Stock NOS from Ford. This must be in the correct order that you are looking for. To overcome the problem, part numbers were updated by changing suffix or updating number year code to reflect in use.

Thanks, Rodney. NOS means it is new and has never been installed on a car. Depending on the decade this is first 3 or 4 alpha numeric characters. Any out of the normal flaws are mentioned and most times even pictured in so there should be no surprises.

For NOS parts the best way is to search use year code as primary. Often times the suffix changed but part design and function did not. To capture an exact phrase use quotes around the phrase, Term1 Term2. In 1970 the US enacted price controls.
