[Double Venom]

Marty,
Man oh man! Rear bushings? Well after many, many, many attempts I finally found out they are from a full sized Chevy, (Impala,etc.) station wagon, circa late 60's early 70's. I suspect you are "Road Coursing" the car? Ever thought about changing the rear end over to a full 4-point with adjustable trailing arms?
(Fabricating-welding brackets could be a little pricey! And of course the geometry has to be perfect!!) If this is your plans, take pictures I have always wanted to do this to an 8.8 .
