Dig It! cool even though I'm not a Pepsi guy (Coke Is It). I'm pretty sure that there was a similar upper paint break on the last project truck from R.B.'s Obsolete-try their website. I think I'd try to follow the line of the fender top, about 6-8" up from fender and then go horizontal about 1/3 of the way down the door. Dude, are you still gonna be happy with this paint in 10 years' time?
