Need a few extrusions

[bmklawt]

Help.

I need a few parts, anybody have some or know where to get it, all the extrusions in my bath are gold colored. I can find new extrusion that will work but I would like to stay close to original.
First picture is of the extrusion that holds the overhead to the wall, I need 6 inches.
Second picture, what am I missing in front of the shower? I need some.
Third picture, what goes over the lip of the tank at the floor? need some of that too.

Anybody have pictures of those areas of the bath so I know what I am looking for
