Door threshold fixings and wheel nut colours, Trying to establish the correct fixings and colour Options

[Bibble]

Hello all, I rather foolishly forgot to take any pictures of the fixings for the door sill aluminium strip (the wide one not the narrow one inside the car) when I took it off about 18 months ago. My car is an October 1971 - 1.7. I know there are pop rivers holder the lower edge on to the car but what goes at the top underneath the door opening seal? Is it rivets again or a small self tapping screw? If it is rivet what colour is the river? And what colour are the lower ones? I understand white on later cars ? But that would seem to clash with the aluminium colour as would Black that hold the rocker on.

Also, what colour were the wheel nuts originally? I have pendrini alloys in silver with black bolts. But the paint on the bolts looks very much a more recent home addition......

Any advice on either subject very welcome (IMG:style_emoticons/default/biggrin.gif)

Best wishes
