Yes.
my notes suggest the following:
(IIRC this was from a combination of personal observations and info gleaned from the internet)
HM = 1973-1976.5
HW = 1976-1978(?)
HF = 1979(?)
The 15x7" Rally II was offered into the 1980's, and could be optional (with different center caps) on the third gen Firebird.
