Quick answer: Identify the installed system before shopping. Save visible part, casting and engineering numbers; compare dimensions, mounting points, connectors and position; and check production or option notes from reliable references.
Use the installed component as evidence
Photograph the old part before removal and preserve labels, stampings and casting marks. A previous owner may have installed a later service replacement or conversion, so a catalog application should be checked against the physical car.
High-risk fitment questions
- Is the engine and transmission combination still the one the car was built with?
- Have brakes, steering, ignition, charging or cooling systems been converted?
- Does the candidate match the old part's position, mounting, connections and dimensions?
- Does a manufacturer catalog support the application, including exclusions or production breaks?
Do not buy from the title alone. “Fits 1967 Mustang” is a lead to investigate, not a fitment guarantee.
Check the car you actually have.
