3-4. General.
Basic engines in M48/M60 vehicles are the same but motor supports, manifolds, exhaust
or cooling systems require different brackets to fit a particular vehicle. Accessories
and brackets must be swapped from the unserviceable engine to make the replacement
engine fit another application.
