Long story short, I'm finishing up an engine rebuild and lost one of the motor mount bolts (Ford Part #N811230-S100) on my 5.4L. I need to know what size (length, threads, etc...) those bolts are but they're hard to find since they've been discontinued apparently. All of the others are already in and tightened so I'm trying to do this without having to take one out. Thanks in advance for any help
