As my radiator is out and had some some time on my hands I decided to start chasing my 80 MPH vibration. I don’t believe it to be my tires as I have rotated them and it didn’t change a thing. So based on a discussion in @CanCritterAnd
@Ross Wooldridge 1971 Plymouth Sport Fury GT Brogham & U code Super Comando mentioned checking the drive line angles.
I first got out my service manual and read through the specs. I started out with a small 6” bubble level with a leveling screw and tried to follow the process.
First issue was finding a flat spot on the engine and transmission. Of course the service manual says use tool SP 5060 and adapters. I don’t have that tool nor does it come up in a google search. The area is tight enough that it is difficult to get a level up there, so I made my own adapter the would sit on the block by the oil pan. This Plywood adapter clears the tie rod and exhaust. This allowed me to measure the angle of my engine and transmission.
