I can't be 100% sure it's a L72 car, but it does have a broadcast sheet with the M22 code and the front/rear spring tags show an L72-only combination (thanks Rick Nelson!). It only has 9800 miles on the odo so a lot of the little stuff is intact, although it is the roughest 9800 mile car I have ever come across .
I am already buying up NOS crap for it so it looks like I will keep it around for a while....
