OMG, this is almost my story. I too had the same 76 Formula back in 1979 while in high school (picture is in my garage), but I unforunately totaled it in November 1979. I wish to God I could have that car back.
I got a 1976 Firebird Formula that was almost exactly like this one when I was 16 (1979). I had to sell it in 1985 to pay for my last semester of college. I regreted it and that why I searched for 2 years to find this original, number matching great car.
