Application and specifications for automotive parts

We are a manufacturer and remanufacturer of automotive parts and need some help researching the specifications and applications of some of our parts. For instance: we have part number 1234-46789-AB and would like to know all the vehicles it fits in, previous versions, specifications (if applicable), and a bonus would be competitor pricing/who else is selling it (and in what condition). This can be done on an excel sheet or on our ecommerce platform: Americommerce. Our parts are for American Brand cars and trucks (Ford, Chrysler, GM). Understanding of automotive parts and familiarity with various automotive sites and resources would expedite the process. The items needed per part number listed in order of priority: Part Number Cross Reference, Application info, older part numbers, other sellers, Prices found across the web. This could potentially be an ongoing project since we are adding new parts all the time.
