I don't agree, replacing everything will cost close to $100 while two of the clips will set you back about $3.50 total. Worth a try isn't it?
Go look at any Chevy Duty catalog page 17. Door latch repair clip, there is a picture in there. The clips and a strike plate adjustments fixed my rattling door problems. Look at your door, see the only moving part, it goes over that tumbler and makes it look like it's original shape.
If it doesn't completely fix your problem, buy the latches and strikes then.
