LoL.... yeh i noticed the same thing.
Been using the plastic wrap example because it magnifies better.
1 B D - any chance you could scan your buildsheet in a scanner ?
Luggage racks only available on big wagons and little wagons.
So far .... it appears 57-2 / 572 is the actual rear spoiler (D80) itself.
Its not listed for GTO in sales order or options list, since it wasn't a factory available option on GTO or Lemans.
But 572 is listed as D80 rear spoiler for Firebird.
And 'some' of the few buildsheets i still have access to are Judges, and some have the D80 spoiler listed in bottom ledger breakout.
Just deductive reasoning for now.
...... to be continued .......
a couple // few more 70-71 Pont Mich Judge sheets would be nice
HELLO OUT THERE !
