Don't use your old rusty mounting bolts when installing front sway bar bushings (if you managed to get them loose without breaking the bolts!).
Our front sway bar bushing mounting hardware kit includes:
(4) 10mm flanged small head bolts (black oxide plated)
Note: G-Body cars require a special built small headed bolt to clear the sway bar bushing clamshell. Our bolt kit is identical to OEM specs.
