With the new plugs, and correct timing, I was able to drive the front end onto ramps and check the undercarriage. The first thing I noticed was this broken Right pivot mount (E2TK3KC90GAL) for the Left beam. Fortunately, I have some spares, and this one (F4TZ3B178A, F4TA3K090AA) from a '96 Bronco is interchangeable.
