You will loads of opinions on brand names, etc. My recommendation? Stick with AC Delco spark plugs. (I think yours requires the MR43T plug... but verify that). STAY AWAY from Champion and Autolite plugs. Many like the NGK brand. Otherwise, replace the points, condenser, (assuming you have points), cap, rotor, wires, plugs. Fuel filter(s) and water fuel separator. If you do not have a water / fuel separator, then install one.
