In response to Dave Darby mentioning this a little further down the board, here are pics of the '56 F100 I did by grafting the Foose roof onto an AMT '53. It's still a custom because I didn't "fix" the chop on the Foose roof.*PICS*
I do have another build in progress on which I fixed the chop to make a completely stock '56, but unfortunately I don't have any pics.
