yea you need the duraspark ignition module and a vacuum advance dist.plus the harnes to join the 2 together.your truck should run better with that combo.the feed back carb talks to the computer along with the dist and the 02 sensor,to adjust your timing and a/f ratio.

this is the duraspark


this is the plug in your harness.that you plug the dura spark into.


this is the harness you will have to get from the wrecking yard,that joins the duraspark to the dist


this is the other end of the junk yard harness that plugs into the dist


this is what the dist you need will look like,with a vacuum advance.i know this is a v8 but it's the same principal.
