Looks like the condenser housing, the tin part the fan housing is mounted to, will have to be have the condenser removed for access. Kinda looks like , 2nd to bottom picture, the housing might separate there. If it's made like a lot of cars, some times the spot welds have to be drilled out and replaced with screws. I'd like to see a little more of the tin where the tubes are coming out.... from the side you're showing and ,same end, the other side.
