Words of warning - use at least a 135 degree tipped cobalt drill bit as Ford tends to use Gr 8 bolts. The junk from your local hardwre store probably wont do it. Here's some drill descriptions from McMaster Carr - and it only takes a couple days to get an order to you - McMaster-Carr
Yep im thinking it needs to be hot, not red hot but hot, and use an EZ out on it. If that doesnt work I guess its off with the head and down to the machine shop :o
