21. Part Numbers
The majority of the parts needed for this swap were only ever used in 1978-1981 GM A body cars, unless otherwise noted. I have tabulated the part numbers for all parts in Table 21-1. Most of the GM parts have been discontinued, however, many are now being reproduced and sold by vendors, such as, The El Camino Store, El Camino Parts, Original Parts Group, or Muscle Cars Only. Parts can also be found in my Garage Sale section.
