Help me decode 72 Charger

Can someone help me out, I'm happy to say that my little brother is 14 and into cars, specificly into mopars......so I guess I have been a good influence.8)

anyway he just bought a 72 Dodge Charger, very solid project, should be an easy resto. Looks like a factory 400 high performance, hemi orange, 8.75 with auto, looks like factory sway bars ect.....anyway heres the the fender tag readout, hoping somebody can decode it.

Also something I saw that was wierd was there was a letter "K" stamped out of the top right hand corner of the fender tag....anybody know why?

The fendertag reads........
