Do I have to weld the new wheelwell panels, or can I bolt or rivet them?
Documented on the Ford Mustang build
Published February 26, 2026
Welding is preferred for strength and to restore structural integrity, but panels can be riveted or bonded in place if welding isn't an option.
Full Answer
Welding is preferred for strength and to restore structural integrity, but panels can be riveted or bonded in place if welding isn't an option. If you rivet or bond, be sure to seal seams thoroughly to prevent rust.
