Mick, welcome. It is always best to start a new thread when changing subjects. You should identify what vehicle you are asking about, i.e.; make, year, model, motor, etc. we are here to help you but you have to do your part and help us. The part you are referring to (starter solenoid) is available as a complete part through the usual venders, LMC, Jim Carter, Rockauto.com, Brothers and most of the rest. Good luck with your project.ðŸ›
