Abstract
A joint for a motor vehicle body comprises a first structural member fabricated from aluminum attached to a second structural member fabricated from steel. The second structural member has an adjoining portion that is in substantially juxtaposed abutting relation with the first structural member when the second structural member is attached to the first structural member. The second structural member has a ramp portion terminating in a bare exposed edge on the second structural member and upon which the bare exposed edge is disposed. The bare exposed edge is displaced from the first structural member to form a gap between the first structural member and the bare exposed edge to prevent corrosion of the bare exposed edge without the use of adhesives and sealants.
