Are those real wheels John? No wait, they're Steve's!
I have been looking at this thread for the last week or so and I'm gonna add my input to it. Here are some pics from my dads old KW he has 8 steels budds and none of them have round holes. If your gonna do all the work to be "scale" them do it right. Steve's wheels are a masterpiece I have his 10 hole aluminum wheels and they are spot on replicas! His steel budds are just as nice and he does them himself one at a time! I also think that a prototype with feedback from us "truck guys" would have been better for these fellows. Good luck!
