quote:would you say if one is doing a rebuild that a removable cross memeber is a MUST do?
It's not necessarily a "must do," but it is a very good idea. Otherwise you can't remove the pan with the engine in the car. And, it's a LOT easier to remove the cross member when the engine is out of the car than doing it upside down from the ground underneath the car.
It also allows you to install the lower chassis stiffening kit which mounts in the same location.
