I bought a nice wire crimper last week. I am about to order and install all new wiring in my 1965 C10 (AAW Classic Update Kit). This wire crimper comes in several different packaging options. Some have 5 crimping dies and mine has 7 dies. It was only $7 more for the extra 2 dies. I think this will be the only wire crimper I will ever need.
