This is a great list and I will pass it on to my son. He has an 88 Power Ram 50 2.6L I can't seem to readily find the spark plug gap for the plugs on the pis site - we don't have a manual with the specs. Changed the rotor and cap last night, will change plugs and wires when we know the correct gap. Thanks for your help. Wasn't sure how to post.byhis question so replied to your post. Thanks again
