| 1. A method of manufacturing an assembly for a vehicle, the method comprising:
forming a first member to include a plurality of elastically deformable locating protrusions extending outward from an exterior
surface of the first member, the forming the first member to include the plurality of elastically deformable locating protrusions
comprises forming a first set and a second set of the plurality of elastically deformable locating protrusions;
forming a second member to define a cavity and to include a plurality of elastically deformable compression features disposed
within the cavity, the forming the second member to include the plurality of elastically deformable compression features comprises
forming a first set and a second set of the plurality of elastically deformable compression features;
the respective first sets and the respective second sets of the plurality of elastically deformable locating protrusions and
the plurality of elastically deformable compression features being spaced apart from each other;
inserting the plurality of elastically deformable locating protrusions into the cavity in press fit engagement with the plurality
of elastically deformable compression features such that at least one of the plurality of elastically deformable locating
protrusions and at least one of the plurality of elastically deformable compression features are elastically deformed to align
the first member relative to the second member according to an average of the elastic deformation between all of the elastically
deformed locating protrusions and compression features.
