It looks just like the bolts in my motor mounts but those are all in I think. Ive been haveing the worst look loosing bolts this time. I lost a header bolt(later found but left the stock bolt in anyways), one of the starter bolts and now I have this extra one. I put in the 4 motor mount bolts and everything else is basically done, just waiting on a fuel line disconnect tool so I can put my radiator back in. Does anyone know what this is from???
