Bigguster, the book mentioned above has been very helpful to me also in the areas you mentioned. It will give you a listing of the tags that should go on coil springs, leaf springs etc. It is also very thorough on code deciphering. Also, go to the home page for this site and find the category "resto shop" on the left hand side. You will find a section in there that lists by part what the finishes should be on the steering, suspension and subframe parts. This was very helpful also. I have not found a source that tells what paint daubs went on which parts and what colors are correct. I have had good luck cleaning these parts and finding remanants of some of the old markings but not always. And if your car doesn't have some of it's original parts, it won't matter. Can anyone else help?
