thanks heaps for the link [saved !!], see below I have taken a chunk of that pic and shown where my nylon/plastic bush goes...the diagram on the site talks of a 'nut' [27] that goes there but look at my pics you can see that that [in JDM case] is the nylon bush ..it sits down in that loop forming a cushioning sleeve..then that whole mechanism slides back in to the bracket on the door pillar and then the 'check pin' [28] slides down thru the lot to hold it all in place...
Moncha I'll take you up on the offer..I am hoping Isuzu didn't change the design for the US model..
Thanks Again
