Door striker post reinforcing

If you swing the door all the way open you rotate the hindge out of the worn position.
The detent spring comes into play and hides the wear too.
Open the door just slightly and lift on it.
If the hindges havent been renewed you can bet the farm on comsiderable wear in the drivers door if not both doors.
I wish there was a good and simple way to reinforce the stricker mount.
