Really mate do not bother.
Take a look at the one on your car by removing your bumper. They are very very very flexible.
Get a rectangular section of steel from your local metal dealer cut to length. Drill 4 holes in it for the retaining bolts and another couple for the rad. Will cost you less than a tenner.
Fit and you will stiffen up the front chassis legs on your motor.
If you want to be a tart you can then get it powder coated.
