If the used Ford Thunderbird component is working well, installing it will not cause any problems. Junkyards and auto recyclers generally have large warehouses filled with used parts that consumers can purchase from.
Older vehicles, such as the Ford Thunderbird, have small markets of parts available. Buying used components is not only inexpensive, but is usually one of the only options available when looking for specific parts. There is a stigma associated with older parts that automatically dictate whether or not they will function properly. Although some parts may be completely worn, auto recyclers often have warranty options available that allow a buyer to test the part and return it if they fail.
When installing used Ford Thunderbird parts, be sure the components fit on the vehicle. Also make sure to clean the components by getting rid of any dried seals that may be stuck on the parts' mating surfaces. Electrical components can be tested with voltage meters to ensure they are sending the correct current through. On a steel component, the surface should be checked for rust or corrosion. Trim pieces need to have the properly sized clips in order to fit securely on the body of the vehicle. If the component is prepped and functions properly, the used part can potentially save the vehicle owner thousands of dollars.
