Are fusion enginges interchangeable or are they specific to a given chassis? Ie. Can you pop the 300-rated engine out of a 4/6 75 tonner and install it in a 6/9 50 tonner? In a similar vein, are enginges from different unit types interchangeable. ie. can I canabalize the fusion enginge from a tank to get an ASF going?
