Help, Need Engine Mount Nut Size

[carjunkie]

I am new here and have done some looking around, but I am not seeing the answer to my question.
I bought a 1996 Mustang GT 4.6L 5 speed. Nice car but it had a few flaws I am working through.
The big one right now is the motor mount is missing the nut on one side. As you can imagine this makes for some bad clunking noises as I bang through the gears.
Anyone know what this nut size is? Metric or SAE? I looks like 1/2 in or so, but I do not want to crawl under this thing 8 times to figure out what it is.
Any help would be great,
Thanks

Prolly best to just order an OEM replacement instead of hitting up the hardware store.

Another forum indicated they are 14mm with a 2.0 pitch.

Good Luck!
