Funny enough, i've been collecting orange pics too for my orange '74.
I was first big on J**P 'mango tango'.. but then started really digging Copperhead. See pic of side by side (Copperhead on right). apologies for posting a j**p pic, but i haven't seen it on an EB yet.
Recently, someone posted Honda's 'Redline Orange' .. seems like a nice deep color too. Bronco pic posted
I think i'd be happy with Sunburst, Redline, or Copperhead.. and will likely come down to if there are significant cost differences. I'd like to paint my engine bay while my body is off.. so I need to decide here soon.
