Undercarriage bolts missing, which are these.
 

My GFs TL has been shaking under acceleration.

After inspection it appears a couple bolts are missing.

I'm not familiar with these cars but it seems to be the connection from the trans or motor to the frame.

Any insight into which bolts these are and spec would be greatly appreciated.
