1966 Dodge Dart

It could be the difference in where the distributor is indexed. My TDC points directly to the rear of the carb. Also I am running my wires in between the other wires going thru the cap instead of around the cap. I can take a better pic of that when I get home tonight and post it for you. As for the switch it is available if you are interested. Just shoot me a PM. The difference between them are the amount of posts to connect to. the first switch I had was 2 posts in the rear of the switch. The posts here are either 3/8" or 7/16" lugs if I remember correctly. One carries current in and the other carries current out. If switch is pushed it kills the flow.
The 2nd and the one I ended up using has 4 posts on the back. 2 large lugs 1/2" and 2 small lugs 3/16" I think. In this pic you can barely see the one small post but the 2 large ones are visible. This allows you to not only run the heavy load thru the large lug but also a smaller accessory circuit thru the smaller lugs. Each of the paired lugs where separate from the other but to push the switch kills power to both outs. Thats about the best I can explain it. I could have made either one work but decided to go with the 4 post. Again shoot me a PM if your interested.
Thanks Rod
