The previous owners did some customization on the motor and I'm having trouble finding parts to repair and replace parts that are needing replaced. Right now I need to get new plugs and wires but not sure what to get as I don't want copper plugs. It currently has autolite 26 plugs in it. The motor has been swapped and upgraded or atleast upgraded. How do I find the proper application? If any other information would help let me know.
