bolt size

[sbrooks]

The bolt from the header to the X-pipes fasteners have come off. Can someone tell me the size of the bolts so that I can get some new nuts ( no pun)? The other side is secure i just notice this today when I was changing my oil

Ford Parts site says M10 X 1.5mm so that should give you a starting point. Just make sure not to put mild steel nuts on there or you will never get them off.

Does anyone know if the stock exhaust manifold bolts that connect the x pipe to the manifold can be re-used for shorty header install. Buddy bought a set of shorty headers that didn't come with any hardware, has Stage 8 bolts for the the header to head but nothing for the collector end.
Thanks,
