has anyone ever custom made their own spark plug wires. I have msd wires, and i was wanting to make sure that i am crimping them right. has anyone ever done them. you make sure the insulation is an 1/8th of an inch past the tabs and the conductor is an 1/8th of an inch past the conductor tabs. the insulation tabs, you are suppose to bend them with needle nose so they crimp better. you are suppose to put the terminal into the w shaped block and then you are suppose to use a vise to crimp it, but it doesnt really say how or when you are suppose to crimp the tabs for the conductor part? i get that the insulation tabs will be crimped from using the w shaped block and the other piece, but how do you crimp the tabs for the middle conductor part
