Wheels are all original Clark, yes there is a difference on that one, but it has the Clark cast markings on the inside of it. Yes the frame does have a bow to it, its bent behind the driver's seat. Someone had very poorly welded a roll bar to it and the frame bent at the roll bar. They then reinforced the frame at that spot making it almost impossible to get the bend out. Tires are Cheng Shin.
Scarabdrew, I'll see if I can get some pictures of the brake and throttle linkages for you.
