Looking for help with restoring a 1970 Charger front bumper grille assembly.

Need some HELP!!!
Anyone know if a good source that would almost show step by step restoration of a 1970 Charger front grille/bumper assembly?  I bought my '70 car some years ago and some of the bumper support parts were missing, bought some spare parts over time so one day I can put all the parts together to put a complete bumper together on my car.  Like to know if anyone knows of a source that would help with taking an inventory to make sure I have all the parts and show how everything goes together.  Any help would be appreciated in advance!

I don't know about step by step instructions but the parts catalog at 70 Charger.com is a great starting point.  See this link:
