he says '71 and '72 ... but the fender tag pic under the '71 shows a '73 tag

Isn't 999 "petty blue"

Interesting panel welding.

A lot of mud to cover that.  Check out the stretch marks in the replacement panel. 
      History on a finished car is huge !!!

999 is special color, something not covered by a standard color code... Which in 72 Petty Blue was TB3...   Got a buddy with a 70 Challenger 999 code that was originally 69 Rally Green...

AAR hood on the '72 Challenger in the first pic 

& any guesses to What Year?  1980??

I'm very curious what the cars color was.  Don't see many 999 paint codes.

it could be some primer, but there appears to be some green on hinges, rear window opening & door handle recess??

but unless there's a body panel around that wasn't blasted - "WE" may never know
