Boys, i am you savior. I am the owner of a MSD DIS-4, which is the only MSD ignition that will work on your cars. its a little much, (346.90) from summit racing, but wel worth it. I dont know the exact #'s, but i did get btter gas milage, and quicker acceleration. This box will work for off-road or street vehicles (what i have). You can order special mounts so it will better handle the terrain if you go off-road. The best place i found to mount the unit, is on the inner passanger fenderwell, way in the corner. The part # is MSD-6215. It was a breeze to hook up, took me about 30 minutes. It comes with the unit and the wiring harness. I can tell you to skip all that reading crap, it confused the hell outta me, just go staight to the diagram, and double check all the connections, and check again, because one grounded dark brown wire, that looks black can keep you stumped for awhile. Well get it, and love it, cause i did.
