Dorman - HELP Exhaust Flange Stud and Nut P/N:03112
Dorman 03144 front exhaust flange stud and nut for the 1979-1993 Ford Mustang and other vehicles holds an exhaust flange joint together. Use it when the original stud or nut is missing or has worn out.
A snapped, stripped or rusted-through stud, a nut that will not tighten, or ticking and hissing from the flange can all point to worn hardware. A leaking flange gasket, a cracked flange or a loose pipe can be behind those signs too, so find the cause before buying.
This front exhaust flange stud and nut also fits the 1985-1989 Merkur XR4Ti and the 1983-1988 Ford Thunderbird. A 1979-1993 Ford Mustang takes one of these packs, which holds two studs and two nuts. Driving something else? Look for your own car in the "Vehicles it fits" section.
