No bolts, just some small slots in the bottom.
I just helped Dave M35 with some info on fitting, I will just cut and paste my response.

Yeh, I had a few issues too. The right hand twist fitting for the top I had to ditch the rubber, the pin was out a little too much. Looks like a manufacturing fault but it works ok.
The fiberglass had to be cut out around the radiator cap, not too much, just use a nice sharp blade so you can remove the cap easily. the fiberglass section must be further away on the G35.
The lower condenser slots are too wide like you said, but it doesn't seem to matter once the top bolts are done up. Just make sure the flat part sticking out stays above the slot then do the top bolts up.
The fan shroud is too short, I had to cut the edge off on the airbox side. Trial fit it before you put the rad in the car, you will see the section you need to remove.
