How do I replace the driver seat belt BUCKLE on 2010 Galant? on 2010 Mitsubishi Galant

Where are the attaching bolts? Does the seat have to be removed? The buckle will not hold the belt when it is inserted. There is no clicking sound, which usually occurs when the belt is inserted and locked. It DOES NOT LOCK.

remove seat to gain access to bolts or poss under car thru floor board there are bolts with plastic plugs over them. coulb be either one
Is it possible to just replace the buckle at the top of the arm or is it a COMPLETE piece?
the whole piece
First try washing it out with WD-40, a bunch of it, use rags to catch excess, while working latch at the same time. Worth a shot!
Ok, thanks
