I've been following this thread since I picked my grandpa's 1971 c10 because its green as well, but has a yellow cab (which I haven't seen another one like it). I replaced dash lights to LED after I saw your post, too. I have my 5/7 drop parts sitting in the garage for a sunny day install. Just wanted to say keep up the good work. I definitely dig it!
