i removed that hanger your talking about. like i said, where the 4 tubes come together, underneath the transmission i think, its really close, coudl that be it? i wouldnt imadgine it would be tho seeing as how everyone who has one would have that problem. however, i didnt think of this at first, but where the header connects to the block, the 4 bolts on top and 5 on bottom, the top middle right nut snapped, so there is not nut there. but there is 2 to the left, 1 to the right, and all on the bottom. could that be it? it seems super tight tho
