interchangable parts list? Help please...

Hi Im new to this forum..I just bought a 78 4dr Impala and I am wondering if anyone knows of a book or link that tells you which part are interchangable?I know 77-79 but up until 90 the body looks really close to the same.I tried arcives but no luck. Example:89 4dr interior in 78 4dr car.Engine, susp.,body ,ect... thanks

it isnt that simple, some parts will ,some wont, some will sorta. the way to know is to have a buddy at a junk yard with an interchange manual.
