[updated:LAST EDITED ON Jun-02-03 AT 01:57 AM (CST)]I am selling a distributor that is in my truck now. I am having a mechanic install one with a vacuum advance on it. It has the 4 wires that come off the side to plug into the computer wires. It's ignition module is the 7 pin one. 5 on one side and 2 on the side by the capacitor. It is non-vacuum advance type. It is working and running in my truck right now. I have a 84 suburban with a 350. So if anyone wants it, let me know. It will be $20 plus shipping. I will guarantee the distributor not to be DOA.
