Hi, while I see the dogbone is there the guy I bought it from said a mount is missing, possibly two. Can anyone point me in the direction of what mounts are missing based on this? Thanks.

The motor/trans mounts are not visible in the photo, as they are below the drivetrain, attached to the cradle.

From the picture, due to the fuel line routing and cruise control solenoid location, I surmise you have an 85 or 86 Fiero.
The engine mount is on the passenger side, attached to the engine on the pulley end and mounts to a bracket on the inside of the cradle.
The transmission is mounted to the cradle at two points, one on the fire wall side and one on the trunk wall side, on the driver's side of the front and rear cradle cross members.
Get it up in the air and check it out.

The only mount visible in the photo is the "dogbone" mount, to the right of the air cleaner. It has a bracket that attaches to the cylinder head, and a bracket built into the trunk wall. The two ends of the dogbone attach to those two brackets.

As mentioned above, the rest of the mounts are underneath.
