I bonded in aluminum pockets I made to mount the BMW side marker lights in the fenders.
The first picture shows the pocket bonded into the backside of the rear fender.
The second picture shows the pocket from the outside. The holes were drilled to help give the epoxy bonding strength.
The third picture shows a press I made to straighten out the slight curvature of the rear marker lights. I sandwiched the lens in the press and then snugged the bolts up. I placed it in a boiling pot of water for a few minutes and then into cold water. The lens was now straight when I took it out of the press. It matches the contour of the fender perfectly now. The front marker lights matched the contour of the fender and didn't need the press.
Fourth picture is the final result.
