The present disclosure provides a method for bonding a structural component to a rail. The method includes (a) positioning a bonding agent in a plurality of blind holes defined in a bottom surface of the rail, (b) positioning a spacer in each of the plurality of blind holes, (c) positioning the structural component into the channel such that the structural component rests on each spacer, wherein a first gap is defined between the structural component and the bottom surface of the rail, a second gap is defined between the structural component and a first sidewall of the rail, and a third gap is defined between the structural component and a second sidewall of the rail, and (d) injecting the bonding agent into the channel such that each of the first gap, the second gap, and the third gap includes the bonding agent.
