67 Barracuda convertible

I just found this thread and have been reading through. Very Impressive. I did have a question regarding the front grill work you were doing and the broken studs. Where did you find replacement studs or did you use a screw with the same threads and just cut or grind the head off. I have several broken on a 68 and I have taken the trim completely apart and trying to figure out what to use as a replacement. Just up the road from you in Richmond, VA.
