Parts interchange

I believe a number of parts in the 92-96 Roadmaster were also used in the Chev Caprice. Does anyone know of a source for a parts interchange manual? That would help people here locate parts which often do not show up under Roadmaster or Buick when using search engines.

I used to use Hollander manuals to look up interchange parts. Many salvage yards used them years ago before the advent of computers and computerized inventory control. You might check eBay to see if any one has any for sale. Another good source for part numbers is the collision catalogs many body shops use when they estimate damage. You can buy pages from the book on eBay specific to your make and model. I own a set for most of my vehicles, and find it easy to use and very helpful when researching a pert number. It also lists dealer prices for the items that the estimator can use in their estimates. These prices may be a little outdated but give a close estimate on the particular part's cost.
