just checked my 72's frame & it definitely does not have the holes in the frame or arm mount.
the hole in the frame for these bars has a captured or welded nut for threads of the bolt, its not the self tapped machine screw type threads like for clamps. the hole in the arm mount is just open for the bolt/nut on the other end. from the pre WS6 cars ive seen & stripped they didnt have the holes/threads for the bars.
maybe some others with pre 78 firebirds or t/a's can confirm if their car has the holes.
