I dug up a pic of my front fender braces ('51 3100) and they also seem a little "curvy" and pretty close to the ones from eBay that Dan posted. I looked at the parts list and couldn't determine whether there was a difference between the smaller trucks and big bolt fender braces. Sorry if I'm muddying the water here, but if the one you got fits, there's no issue. Although the wheel opening is larger on the big bolts.
