On my valve covers - First I moved the oil fill opening to the center of the cover and welded shut the hole created when I cut it out. Then, I made 8 mounting bars and drilled and tapped them at a spacing that matched the coils and welded them to the valve cover. Also then made 16 standoff tubes from 3/8 stainless fuel line - They're about 9/16" long. Bolts go through the coil heat sink, through the standoff and thread in to the mounting bar. Welds are kinda hidden under the coils.
I ordered a Ford sensor cause it sure looks like it'll fit right on the Jeep housing - we'll see.
Got the O2's fired up and working. Going to start mocking up wiring runs in the car now.
