I redid my intake today, cause I broke a intake manifold bolt, and I need to take intake off to take out that broken bolt, I broke another one today again, im plan go ahead and replace all the old bolt, ford dealer charger $5 a bolt and they sell in pack of 10, so it $50, IM REFUSE to pay that, any one know what is side and length of this bolt, that I can buy it from ACE hardware store, thanks
