When I did my V8 swap I cut out all the wires I didn't need, the ones I had left I ran along the firewall like it should have been to start with. If you want I'll take a pic of it and post it up tomorrow. As far as cutting out the inner fenders I've been wanting to do that to mine, but I've been a bit nervous to do it. If I do decide to do it, I'm taking it all out all the way to the fire wall. That way I can attempt headers. I'll also make some kind of hoop brace that goes thru the firewall and will tie into the cage once I get that far. 8)
