What parts make up a car suspension?

During the 1950s and 1960s, interest in the hobby peaked, as many companies started to profit from the interest in the promo cars. AMT, Jo-Han, Revell and Monogram started producing model car kits during this time, and it was considered a "golden age" for model kit cars. Most of these kits were known as "annual" kits, kit versions of the promos that represented the new cars that were introduced at the beginning of each model year. AMT, Jo-Han and later MPC were the primary promo manufacturers. In addition to building them stock, most annual kits were known as "3 in 1" which allowed the builder to assemble them as stock, custom, or racing versions. Model Products Corp. joined the kit/promo business in 1965. Among their first annual kits/promos, was the full-size Dodge Monaco, which was released with a gold metallic painted body and is a valuable collector's item today. These plastic models were intricately detailed, with body scripts, trim, and emblems, as well as dashboard details, exact duplicates of the real thing, in 1/25 scale. Typically, each automaker would license their cars to one model company. For example, Jo-Han produced Cadillac models and promos, AMT did Chevrolet and Ford cars. Often these companies would change, for example Jo-Han produced the 1972 Ford Torino, and MPC did full-size Chevrolets in the early and mid 1970s. Typically, the kits had more parts and details than the promos. For example, kits often had opening hoods, separate engines and suspension parts, while the promos were molded with hood as part of the body, and chassis with metal axles and one-piece chassis with suspension details molded in. 1969 and 70 Chevy Impala kits were made by both MPC and AMT.
