You're thinkin' is right up my alley Jerry. Searched for a
couple of hours last night and another this morning for damper
springs and the only one that I came up with, were a $50 pair
for a Mopar.
Thought of the screen door springs also even though they are
no where near the tension of the original damper springs but
you're right, any thing to upset the harmonics should work,
just to prove the point. Even thought I might attach a piece
of heavy rubber with two opposite tension springs to balance
out the weight of the springs.
Got painting to do this afternoon and it's raining today and
most of next week, so I probably won't get a chance to try
anything till next week.
