Sorry, I guess I didn't really answer your question. I've collected suspension upgrade parts for gbodys for over twenty years.
For 34 mm and 36 mm hollow bars , look for 82-92 Z28 's and Iroc Camaros. Also Formula and Trans Am firebirds.
For F41 front and rear sway bars, look for Monte Carlos and Cutlass's.
The Cutlass usually also has jounce bars and sometimes core support x braces.
The 81-87 Grand Prix will have a Gp bar which is also a popular though hard to find brace.
The Regal and the Malibu typically did not come with any of these upgrade parts, but like all GBodys, these parts are all simple bolt ons which immensely improve the handling characteristics of your car...timo22
