GM-51007-10 is a pair of engine support adapters that are used with components from either GM-28467-B or GM-51007 engine support fixtures when required by published service information. Either adapter can be installed on the left or right, and is placed onto the inner structure of the engine compartment with a cross-vehicle bar between the adapters, typically GM-28467-518 or GM-51007-1.
Other components are used as directed by the appropriate procedure to support the engine. Failure to follow published procedures will result in component damage.
