Electronic Ignition Conversion Kit from Jegs. Questions..
Take the old dist cap off and notice where the rotor is pointing before you remove the old distributor so you don't install the new one 180' out.
When I installed mine I didn't put the distributor down far enough because the O-ring was so tight. Look back there and make sure it is seated all the way down to the block so that the shaft is all the way into the oil pump gear shaft.
