has anyone ever researched all the different smog items part numbers  or shown detailed pictures of each part?

I've started cataloging the parts, pictures and changes but have not finished it completely. Can get confusing comparing what is is writing (documents) and what is found on original cars and systems. Don't know any solid information out there that has been published. 

At least with the GT350 systems you only have a few months of production

There are a number of changes during the production year for the Mustang 390 and the 67 GT500 where parts were changed, added or removed
