Can someone please tell what the two bolts on the front door opening side are supporting. One is missing and the other is loose and I cannot find what they are supporting
Are you referring to the three bolts on the door holding the door latch mechanism ?? if so, then they are holding the door latch mechanism. Or are you referring to the two hex bolts down further on the door frame which I would think are possibly something to do with the window slide/mechanism or central lock mechanism. I don't really know just a guess. Meant to be there so best to get a new one and tighten both.
About 300mm below the three are two bolts about 6mm I reckon. One is missing and the other is loose and I cannot seem to tighten it and am wondering if there is a nut on the ither side which would required ti take the door interior panel off to get to.
I would remove the door trim and have a look. http://forums.justcommodores.com.au/holden-commodore-how-tos/70606-removing-vy-vz-door-trim.html
