And I think Quartermaster or Quicktime has a 6 bolt bell to the old top
loader. And they wont require bashing the fire wall to pu it in I'm
told. The Performance Products dampers are a great looking item. I just
bought one for the Sunbeam LA+SR car's next motor. SFI version and it
turns out that the imbalance weight is removable. And the convert to a
neutral or zero balance item. Want to use your 28 oz unit on a 302,
simply swap the weight.
as in all things YMMV
