BOTH pieces must be located and oriented where there is good support; not always easy, but pretty much required. If the location of one results in a bad location for the other, then the first needs to be relocated or modified.
If relocation is not possible, then how about a larger aluminum plate (1/8" thick, painted) attached (using screws or pop rivets) to either the wall or the door to give additional support where is needed?
