knocking in the rear

[NZ fan]

i read a post recently where someone had a knocking in the rear. I too have had this issue for the last six years or so. after checking everything repeatedly over the years i decided it must be the chassis bolts under the fuel tank. today i decided to have a look. i ran the tank down to about 1/4 then removed the mounting strap bolts and the filler neck which allowed me to open up a gap between the tank and the bulkhead and have a look in there. to my delight i found that one of the body to chassis bolts had been rubbing on the tank and worn an appreciable mark in the tank! [the factory dent in the tank was too low] my solution was to lay a thick layer of felt under the tank and up the bulkhead. so i put it all back together and went for a drive and guess what?? the noise was still there! so i thought... the noise is right behind my head? so i reached back and put my hand on the drivers side hood stay bar which i could feel moving as the noise occurred? i unlocked it [by pulling it over centre] as i was driving and guess what... the noise stopped! not sure what the permanent fix will be but happy to have found it and feeling a little silly for not trying this years ago? so anyway if you have this problem try this simple test and it my be the problem. cheers to all!

My passenger side hood stay rattles. Not sure what to do about it but these things are far less concerning once you know what they are.
