Looks good. I think the calipers painted upper body color will look good. The wheels should be either the same color or maybe even a gunmetal, or maybe polished.
You could go with anouther green for the pinstripe. Like a brighter, more bold green. If the bottom was the right shade of grenn, orange would have looked good too.
Wow I never thought I'd see the day when that thing would actually be two tone...what was that, 2 or 3ish years ago when that idea popped into your head? lol Good to see you finally got her there.
As for a pinstripe, if you want something that's not crazy I would go dark purple as an ode to the old car, and purple looks real purdy with green. Something about them being complementary on the colour wheel or some business like that?
