Mystery vibration at 25 mph can't be diagnosed. It's not the front end!

Yes, starting from ground zero. Bought jack stands and creeper on sale at tru-value. All for under $55. The creeper is cool it unlocks and becomes a seat for when you pull those wheels and do your own drum brakes. If I still had my wife, she could help me bleed the brakes and help out with other things. She helped me put the engine back into good sorts after I bought it. I miss her.
Lesson learned from creeper seat. There is a strap, used for raising and lowering it to creeper mode. One hand on latch, other on strap. Dont learn the hard lesson. It hurts.
