That's good news!

 

I installed the revised parts yesterday, and it still rattles a little bit, although not nearly as much. Btw I have the 401 shift ball

 

I have yet to try this, but try putting a strip or two of Dynamat on the reverse mechanism as I believe that is what is rattling.

 

Installed the Blowfish unit with revised bracket and a Steeda tri ax today. Quick drive out into the country with some WOT pulls and then legal limit driving on he way back into town showed no signs of noise or vibration. Pretty happy so far!
