Welcome to the world of growing action brackets. This has been discussed a 
number of times over the last couple of years. I was one of the last ones 
with this problem.

You need to contact Young Chang, give them the model and serial number, and 
they will send you out a new set of action brackets, and they will pay you to 
put them in.
