[6pack] Shimmy at 50mph

[John Mitchell]

    I've always wondered about the exhaust hanger that connects to the 
transmission on overdrive cars.  It's just a metal hangar with no rubber 
isolation and it's bolted to the rear of the overdrive.   Has anyone 
tried anything to isolate the exhaust from metal on metal contact with 
the transmission?  I'm wondering if it would cut some of the vibration 
felt at the shifter.  John Mitchell  76TR6
