Hi Jeremey,
If you look at the photo from the install in the first pic looking from the top of the intercooler you can see the 2 steel plates that stick out going back towards the car.
They are used to mount the intercooler back more,you will have to cut them up yourself they are not very long at all,and what they do is give the front of the intercooler space to sit behind but still under the reo(reinforcement bar) and add support.
Use all mounting locations on the intercooler.
I have made up a ''top veiw'' paint program drawing to give you an idea.You can see how the intercooler sits behind the front of the reo but still underneath it.Also the top of the endtanks of the intercooler sits snugly between the headlights giving you a good central mounting location.Im not to sure but i think that the brackets can sit under the reo bar or on top.But definently as in the pic they can sit on top.

The intercooler can also be mounted further back.The intercooler doesnt nessesarily have to be mounted half/half under the reo like in my drawing.That is unless you have somthing stoping it like an oil cooler.
Thanks to paulr33 and anonomous for the pic donations.
