Trans mount to trans bolt size?

[Booksix]

I was going over some things on the car and realized one of the two bolts holding the transmission to the mount is missing. I was about to pull the other one to take to the hardware store but remembered that the 5.0 + T5 was a tight fit in the 'bird (as far as getting the trans/x-mem in place) and I'm worried if I pull the second bolt out it will give and my holes won't line up. I don't want to have to pull the x-member to finish this up. Anyone know what size that bolt would be? Thanks!

Well, i have one in front of me, but i don't have the proper tools to measure it correctly.


It's 1.1" long and the width of the outer thread is 0.592"

I also count 13 TPI with my thread pitch gauge

Thanks! I can probably get a good idea from that...
