Abstract: For turbo-diesel application trucks, it is desirable to enable the quickest exit of the exhaust from the engine because, in most cases, the exhaust gas temperatures of these engines are very high. Thus, a hole is formed in the hood of the trucks and the exhaust stack is slid through the hole to permit the quickest exit of the exhaust into the atmosphere. However although the hood may be non-horizontally oriented, the stack should be kept in a vertical position. Thus, a stack mounting basket is positioned beneath the hole having three widely separated outwardly extending threaded bolt extensions that are positioned within three slotted downwardly extending elongated members affixed to the hood. The relative positions of the elongated members with respect to the threaded bolt extensions are adjusted, and nuts are tightened over the elongated members to permit the stack to maintain a vertical orientation.
