GM-28467-300 has two adapter feet (GM-28467-301), and is used with existing GM-28467-B engine support fixture components to support the powertrain during transmission or mount service. Fits Chevrolet Sonic, the Spark, and the GMC Acadia. Required for Acadia due to limited clearance between the outer fender and inner fender. Some build variations may require removing the rubber foot from the leg of GM-28467-301 for clearance.
