Auto's have a removeable cross member and do not have a clutch Z-bar tower.
The rear cross member in '75 was 2 inches wider than in '74.
Passenger side behind front wheel has both GM part# and A.O. Smith part#.
Serial# is stamped on let side rail just forward of #4 body mount and also on left side rear kick up above the wheel area just forward of the #3 body mount bracket.
