Changing white roll-band frame?

Hi,

I'm trying to make the white border frames around the roll-bands dark grey. Here's an animated image showing the parts I mean:



I've tried making the image of the destination box frame on the repaint grey (bottom right-hand corner of the texture, where the headlight texture is) but it hasn't changed it in-game. What texture do I need to edit (and what part if there's multiple parts of that texture)?

Thanks in advance.

Sorry Luke, I can't help you.

lol, I've thought of a way around it but it's not quite what I intended... could paint over the glass on the repaint so it covers the white parts with black (but the white frame will still be behind it).
