Ok, so someone took apart too much of the car and didn't mark the screw correctly and now putting the Xj6 Boot back together and no idea which screws hold what on such as the lights, number plate, chrome etc. Flathead or phillips? I can't seem to get enough of one type of screw to do four screw-holes identically, for example. The folly of being convinced that you'll 'remember because you put those ones over there eight months ago'....

 

no flatheads for sure, and not phillips but posidrive which look like phillips.

the tail light assemblies go on with 3 large phillips ( posidrive ) screws each..

the tail light Lenses go on with 4 chromed posidrive screws each and each screw has a black rubber shoulder "gasket".
