missing a bolt that holds the tranmission to the engine block

[rubix777]

I'm missing a bolt that holds the tranmission to the engine block. It is a fairly large bolt, probably a 17 or 18mm that is very close to where the driverside axle meets the transmission. When looking under the car it is about 2 inches toward the front of the car, and 1 inch down from the driverside axle. You have to remove the towing hook to get to this bolt.

If anyone could tell me the dimensions and length of this bolt I'd really appreciate it.
