it has some decel buzz but i figured out its the same with others...still holding on strong with no bad side effects.

 

I have the clutch and I have no buzz.

I assisted with the install...

-Didn't touch the sway bar brackets
-Only way to get that dam starter bolt is to swing the alternator over a bit
