UPDATE. All seems good enough for now. My oversight and approach was somewhat lacking. There was extra weight in the back of the wagon all this time. Nothing broken or out of place at either L or R coil spring/shock mounts. Both shocks are still good. Left spring does sag but only just a bit. I got the car on a level driveway and took photos. And I was I was able to temporarily get my fuel pump working again when the car wouldn't start this morning. Voltage was getting there, but motor was at a "dead spot" on the 34 year old orig fuel pump. So I reversed the polarity and spun it backwards for a few seconds. Then it was working as normal. Yes, I do have a Ford F150 electric fuel pump, but never got around to installing it. Need to check it for fuel line fitting adapters.
Thanks
