Glad you think you got it!

So you think the springs are bad? You started the post by saying "All is original". Even if the springs are weak the pinion angle should not have changed drastically. You even have talked about referencing other vehicles for the angle. I can understand that if the springs are junk you could have these issues. Seems you could have easily determined there was an issue long ago just looking at the springs and inner liners, are they still there? Mine still has the "Original rebuilt springs" and never had pinion angle issues before or after rebuild. Hope your not throughing more good money for bad at it.

What are you referencing when you say inner liners? Springs in stance and appearance look no different than my 71 or 72 Cudas. In 40 years of working with and restoring lots of 68-74 Mopars I have never had a spring issue that effected the cars performance. Juts been lucky to this point I guess. However I can't deny the fact that when I put that 2X4 between the snubber and the floor to prevent any rear positive load change, car did not shake. This car also shook with the old clutch.
