UPR - K-Member J-Nut 4pc Set (fits 79-04 Mustang) UPR - 2025-105

     Complete the Restoration of your cars front suspension with these OEM style K-member J-Nuts for your 79-04 Mustang. These J-nuts slide onto the lip of the upper front subframe and stay in place when installing the 4 main K-member bolts. The stock J-nuts rust and fatigue over time, not surprising for hardware that is 40+ years old in some cases. Made from the same strength material as the OEM hardware with a clean black finish for a factory look to your car. This style J-nut allows the nut to stay in place while you tighten your K-member from below so you don't have to mess with a wrench up top.
