Terminator Endoarm questions

I´ve found a T2 endoarmkit in my basement last week.I´ve bought it a while ago from ebay.

But I need some parts and have a question about the best chrome color.

I´m using some pics from other guys here hope thats ok.;-)

First I need this part for the front of the arm..it is not in my kit..what is it?And where can I buy one for my kit?:





After that I need the screenacurate wires.What are the right wires and where can I find them?On the T2 pics you cannot really see the texture of the wires.

And I´ve seen this part from a guy years ago on his arm..is that screenacurate and what is the part?:



And on the pic you can see,that he used a great chrome color,too.On one of his spraycans stands "SPAZ STICKS"-What is the best chrome color for the job?I think his one is looking very good.
