coil mounting location ?

[ols0051]

I've got a set of ford racing wires and they came with two types of coil wire. The shorter wire is a socket type fit into the coil, and the longer wire has a adapter fit onto your tfi type coil. The shorter wire doesn't like to stay on the coil real well, and to use the longer wire I have to put some cheap adapter that I got from msd on the coil. It is a plastic tower with a bolt in it with some fine wire wraped around the bolt head. But I think the short wire is the way to go. I guess if the coil takes a crap I'll just have to get another one and move it farther away from heat and vibration.
