I recently purchased an '86 360 D150 automatic. I decided to check the timing, and couldn't find the timing marker to match up with the damper. Eventually I found the marker plate with the magnetic tube on the underside of the engine. Is this someone's "fix?" I noticed someone on another forum mentioned when a steering pump was changed it altered the timing plate location because of a different model pump. Is this the likely issue or is this plate supposed to be on the underside of the car....? tnx psg
