How can I secure the hood on my 389 better?

The hood shakes side to side and up and down too I think, when going down rough roads or over train tracks the feeling and noise it makes is disgusting. Went down a side road a little while ago and thought the hood was going to break off. I already changed the hood pin bushings and found 1 was worn right through. But the new bushings dont seem to hold the hood any tighter. Maybe I didnt tighten the bolt going through those pins enough? Im worried about over tightening and damaging the flange on those bushings cus its just plastic but still I tightened as far as the threads would allow me and then backed off a half turn or so to line up the nut with the hole for the cotter pin.

 

I slow down a lot probably more than I need to even because I hate the noise and feeling

 

Yeah I do this also it stops the squeaks but the noise I'm referring to is more like a banging from the hood shaking and hitting those pads back and forth

 

The good latches arent adjustable maybe they are old and loose though. The shaking originates from the nose of the hood though
