The cylinders are numbered the same, it's just the firing order that's different. You don't need to buy anything new or different, all you have to do is move 4 spark plug wires on the distributor cap. Trace the wire going to cylinder #5, and unplug it from the cap. Next trace the wire going to cylinder #3 and unplug it from the cap. Now plug each one in the other ones old place on the cap. It's easy because they are directly across from each other on the cap.

Now do the exact same thing to the wires for cylinders #4 and #7.

That's it. You're done.
