Also on top of being a 74 you can only use 74 260z door trims as the lock snib is located about 2 inches further back then the later ones.
So 280z ones will not fit.
The ones on yahoo that gav is talking about are for the later doors.
I have seen one door trim for sale in aus for early 260.... I bought it.
And I have seen a pair of nos trims on yahoo for $1600 plus shipping,duty,street ears commission ..
I was at about $2000 when I told Jess not to worry about it.
Cheers Doug.
