OK, I took the time to peruse my NCRS judging manual. So here goes:
Base with manual tranny ----Aluminum rad with an aluminum expansion tank.
Base w/AC and or automatic tranny & all L46------Copper rad and NO expansion tank.
Looks like it the car came with an aluminum radiator, then it had a metal shroud and and expansion tank.
Copper radiators came with the plastic shroud and no external expansion tank (except big blocks).
That's for 70, 71, and 72.
Only the base engine with a 4-speed and all the big blocks came with an expansion tank.
