Review on 🔩 E-Z LOK EZ-450-8 Threaded Inserts for Metal: M8-1.25 Installation Kit, Steel, Black Oxide - The Perfect Solution for Secure Metal Fastening by Johnathan Stoner

Better to replace the bell or spend $400 on a Timesert Bigsert kit when someone tries to crank a Ford 7.3 starter and fails miserably. The set ears are a little fragile though, make sure you have enough depth to run the tap past the tapered tip or invest in a bottom tap if you don't have depth. The drill that comes with the kit is rubbish and doesn't hold well in aluminum, but will do for a hole or two.
