Unfortunately, Niether the Y-99 package nor the 15" wheels were available on the "A" body Convertibles in 1972. I am not sure why, but all of the factory literature that I have researched over the years reflects that. My convert does have the Y-99 big fat
(1 1/8" diameter) beauty of a rear sway bar on it and it appears to be original. I can only assume that this was dealer installed though since all info seems to reflect that it was unavailable on converts. I can assure you that I will be leaving that in place as well as the 15" KR's. It makes those 72's POP!
Oh, by the way Gary, I will give her a bath when I'm done pal. No reason to have to deal with any slop.
