You can get T-bolt clamps on eBay on the cheap, like 16 for $25. They're just as good as any other to bolt clamps, it's not a high end item, save yourself some money. As far as the lower front grills, I don't think they'll fit because your pipes are sticking out too far. You'd have to reduce the pipes first, but since your replacing clamps and taking off the front bumper, it might be a good time to do it all at once.
