Optional accessory on executive, standard on Acclaim and other lux models. Was standard on my Acclaim until some *#@hole snapped it off at the guard surface. They do it for kicks. I have a size twelve steelcap kick I would like to give anybody doing this cr*p. Being a cheapskate pensioner, I just got a Tarago straight aerial and jammed it in the hole the idiot left. Works as good or better than the original.
Hot-Rod, I was only referring to the VT which I have the factory service manual for. Don't know a lot about the VX. My next car will be a 760li 6l V12 (when I win Lotto) so really do not know a lot of stuff about later Commodores except what I hear on this forum, some of it contradictory.
