The throttle cable bracket is of a new compact design for '72, the short legs bolt with two small bolts straight down to the intake. '70 & 71's (exc '71 455 HO Ram air) use the A-G stamped 4 bbl throttle bracket where one leg is bolted to the studded intake bolt. '69 and '68's used the T-4 4bbl throttle bracket, same attachment. Earlier GTO & v8 Tempest/LeMans used similar brackets, mounted in like manner. On a points ignition '72 Pontiac V8, that small studded intake bolt can only mount a mtg bracket for the coil. The '72 I have the most detailing experience on is my T/A's factory unitized distrib WM engine. Will confirm on the Lux LeMans partscar, it is totally original.
