Hey everyone,
I was hearing a thunk from underneath my truck and went to look, and the transmission bolts to the rear mount were gone! I'd like to buy new ones (and possibly a new mount?) but I can't figure out what the thread size is. The ones I'm looking for are the ones that go into the transmission, not the crossmember. It's a 2wd transmission.

Thanks for any help guys.

 

Probably 12mm, 14mm, 1/2", or 9/16".
